Ok did some more research.

While this confirms my confusion (missing better words here..), I learned some new things allthough most of it was known.
Asdide the fact that 'echo' is both, for some reason I always thought that /bin/echo was the echo used when calling echo, and thus not realized the builtin existed - or that they are different 'code'.
How to distinguish between builtin and external util? (e.g. echo) - Unix & Linux Stack Exchange


This one here seems to confirm my most recent assumptions as since today:
shell - Which are the standard commands available in every Linux based distribution? - Unix & Linux Stack Exchange

That I most likley could rely on the bash builtin 'echo' for the use of SWARM.
But none of that sounded certain, so I then I followed a link of the 2nd post (46 up votes) about the standarized commands by PSIX and ended up here: echo

Now, when you go down to the 'Application Usage' section, you'll see this part:
Code:
It is not possible to use echo portably across all POSIX systems unless both -n (as the first argument) and escape sequences are omitted.

The printf utility can be used portably to emulate any of the traditional behaviors of the echo utility as follows (assuming that IFS has its standard value or is unset):

The historic System V echo and the requirements on XSI implementations in this volume of POSIX.1-2017 are equivalent to:

printf "%b\n" "$*"

The BSD echo is equivalent to:

if [ "X$1" = "X-n" ]
then
    shift
    printf "%s" "$*"
else
    printf "%s\n" "$*"
fi

New applications are encouraged to use printf instead of echo.

Now my final question, which of these 2 examples would you recomend?
I have to ask this, because I lack the practical experience of actual daily usage on different systems.

Anyway, I'm going to try this out now.
Lets see which works better as expected.

At least I know now that it wasnt a waste of time preparing $ECHO to use printf, what a relieve! Smilie

Net::Google::Code(3pm)					User Contributed Perl Documentation				    Net::Google::Code(3pm)

NAME
Net::Google::Code - a simple client library for google code SYNOPSIS
use Net::Google::Code; my $project = Net::Google::Code->new( project => 'net-google-code' ); $project->load; # load its metadata, e.g. summary, owners, members, etc. print join(', ', @{ $project->owners } ); # return a Net::Google::Code::Issue object, of which the id is 30 $project->issue( id => 30 ); # return a Net::Google::Code::Download object, of which the file name is # 'FooBar-0.01.tar.gz' $project->download( name => 'FooBar-0.01.tar.gz' ); # return a Net::Google::Code::Wiki object, of which the page name is 'Test' $project->wiki( name => 'Test' ); # loads all the downloads $project->load_downloads; my $downloads = $project->downloads; # loads all the wikis $project->load_wikis; my $wikis = $project->wikis; DESCRIPTION
Net::Google::Code is a simple client library for projects hosted in Google Code. Since 0.15, Net::Google::Code offers google's official issues api support. Besides the new "Net::Google::Code::Issue::list", "Net::Google::Code::Issue::Comment::list" and <Net::Googlel::Code::Issue::load_comments> methods, which use the api from start, you can set $Net::Google::Code::Issue::USE_HYBRID to true to load, create and update issue with the api too. But the official api is not function complete yet( e.g. no attachment support, can't merge, etc. ), Net::Google::Code will back to the scraping way to accomplish those stuff. ATTRIBUTES
project the project name email, password user's email and password, used to authenticate base_url the project homepage base_svn_url the project svn url (without trunk) base_feeds_url the project feeds url summary description labels owners members INTERFACE
load load project's home page, and parse its metadata parse acturally do the parse job, for load(); load_downloads load all the downloads, and store them as an arrayref in $self->downloads load_wikis load all the wikis, and store them as an arrayref in $self->wikis issue return a new Net::Google::Code::Issue object, arguments will be passed to Net::Google::Code::Issue's new method. download return a new Net::Google::Code::Download object, arguments will be passed to Net::Google::Code::Download's new method. wiki return a new Net::Google::Code::Wiki object, arguments will be passed to Net::Google::Code::Wiki's new method. DEPENDENCIES
Any::Moose, HTML::TreeBuilder, WWW::Mechanize, Params::Validate XML::FeedPP, DateTime, JSON, URI::Escape, MIME::Types, File::MMagic INCOMPATIBILITIES
None reported. BUGS AND LIMITATIONS
No bugs have been reported. This project is very very young, and api is not stable yet, so don't use this in production, at least for now. AUTHOR
