=head1 NAME

Acme::AllThePerlIsAStage - Grok perl stages for scripts and modules under use and require–uncompiled and compiled

=head1 VERSION

This document describes Acme::AllThePerlIsAStage version 0.01

=head1 SYNOPSIS

Compare output points to see what-happens-when in order to understand why and decide on what to do:

    perl -e 'use Acme::AllThePerlIsAStage;'
    perl -e 'use Acme::AllThePerlIsAStage;'
    perlcc -e 'use Acme::AllThePerlIsAStage;' -o tmp/use
    ./tmp/use
    ./tmp/use
    perl -e 'use Acme::AllThePerlIsAStage ();'
    perl -e 'use Acme::AllThePerlIsAStage ();'
    perlcc -e 'use Acme::AllThePerlIsAStage;' -o tmp/use_no_import
    ./tmp/use_no_import
    ./tmp/use_no_import
    perl -e 'require Acme::AllThePerlIsAStage;'
    perl -e 'require Acme::AllThePerlIsAStage;'
    perlcc -e 'require Acme::AllThePerlIsAStage;' -o tmp/req
    ./tmp/req
    ./tmp/req

=head1 DESCRIPTION

Sometimes the stages involved in perl’s execution can be hard to grasp. It gets even hairier when you start compiling your code.

When trying to explain and then demonstrate what was happening I found myself writing scripts and modules to output what perl is doing where in order to find out if my understanding lined up with reality. Then to see how reality held up once compiled...

Finally, making a set up every few months got old and I thought I’d put it all on CPAN for the masses to enjoy/ignore.
