ok, so replace spaces with newLine, sort, and replace newLines with spaces?
How about that?

NAME
Perl::Critic::Policy::Variables::ProhibitAugmentedAssignmentInDeclaration - Do not write " my $foo .= 'bar'; ". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Variable declarations that also do initialization with '=' are common. Perl also allows you to use operators like '.=', '+=', etc., but it it is more clear to not do so. my $foo .= 'bar'; # same as my $foo = 'bar'; our $foo *= 2; # same as our $foo = 0; my ( $foo, $bar ) += ( 1, 2 ); # same as my ( $foo, $bar ) = ( undef, 2 ); local $Carp::CarpLevel += 1; # same as local $Carp::CarpLevel = 1; state $foo += 2; # adds 2 every time it's encountered Such constructs are usually the result of botched cut-and-paste, and often are bugs. Some produce warnings. CONFIGURATION
This Policy is not configurable except for the standard options. AUTHOR
