Yes, practice. It would probably be useful to look over some books. The page at
Perl - Programming - Books & Videos - O'Reilly Media lists an abundance of books.
An older list for scientific computing is available at
recommendations on scientific computing with Perl
If you write a lot of
perl, look into the utility
perltidy, it will save you many times over. Always look in your repositories for perl codes, there are a ton of libraries available. You might find some things at
The Comprehensive Perl Archive Network - www.cpan.org that are useful. I never install anything in my system unless I use the package manager (apt-get, yum zypper, etc), but rather I put codes in
~/bin, and
~/executable.
We used O'Reilly books in the perl classes I taught. You are out of the beginner state when you have written 100 non-trivial programs (
drl's rule ) I'd recommend
Learning,
Intermediate, and
Mastering for a full course. You didn't say what your field is, but if it's the life sciences, then the
Bioinformatics might be useful.
A few books from publisher Manning are also useful,
Data Munging, and
OO perl.
However, before you start on this, you may wish to compare perl and Python, say from
The Fall Of Perl, The Web's Most Promising Language
Best wishes ... cheers, drl

uri::url
URI::URL(3pm) User Contributed Perl Documentation URI::URL(3pm)
NAME
URI::URL - Uniform Resource Locators
SYNOPSIS
$u1 = URI::URL->new($str, $base);
$u2 = $u1->abs;
DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to
be distributed with the libwww-perl library.
The following differences exist compared to the "URI" class interface:
o The URI::URL module exports the url() function as an alternate constructor interface.
o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase".
o The URI::URL->newlocal class method is the same as URI::file->new_abs.
o URI::URL::strict(1)
o $url->print_on method
o $url->crack method
o $url->full_path: same as ($uri->abs_path || "/")
o $url->netloc: same as $uri->authority
o $url->epath, $url->equery: same as $uri->path, $uri->query
o $url->path and $url->query pass unescaped strings.
o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters)
o $url->params and $url->eparams methods
o $url->base method. See URI::WithBase.
o $url->abs and $url->rel have an optional $base argument. See URI::WithBase.
o $url->frag: same as $uri->fragment
o $url->keywords: same as $uri->query_keywords
o $url->localpath and friends map to $uri->file.
o $url->address and $url->encoded822addr: same as $uri->to for mailto URI
o $url->groupart method for news URI
o $url->article: same as $uri->message
