Is that clearer now? If you want to remove the leading space from field 1, additional measures must be taken.
OK, thank you so much. I was under the impression that the field separator value was set to the *string* "][" rather than "]" or "[", thus I thought that $1 in the code would have been PS028,006 [KJ <Cj>, rather than PS028,006. This was very helpful. Thank you for taking the time to explain this.

Perl::Critic::Policy::Modules::RequirePerlVersion(3)	User Contributed Perl Documentation   Perl::Critic::Policy::Modules::RequirePerlVersion(3)

NAME

       Perl::Critic::Policy::Modules::RequirePerlVersion - Require a "use 5.006;" or similar.

AFFILIATION

       This policy is part of Perl::Critic::More, a bleeding edge supplement to Perl::Critic.

DESCRIPTION

       As Perl evolves, new desirable features get added.  The best ones seem to break backward compatibility, unfortunately.  As a favor to
       downstream developers, it's good to state explicitly which Perl version will not be able to parse your code.

       For example, the "our" keyword was first appeared in a stable Perl in version 5.6.0.  Therefore, if your code employs "our", then you
       should have a line like this near the very top of your file:

	 use 5.006;

       or

	 use v5.6.0;

       The former is preferred as the latter can trigger v-string compatibility warnings.  (If someone could please explain that to me, I'd really
       appreciate it!)

       Additionally, it's good form to state that minimum version in your Makefile.PL or Build.PL file.
