[Purdue-pm] interpolate perl variables in pod

Another followup to Rick's message about sharing Perl
variable values in Perl and POD.
As JavaFan and GrandFather have already mentioned, no, you can't
directly. However, there's nothing to stop you from generating a POD
document from a perl script:
open (my $pod, '>', 'filename.pod') or die "Can't write pod file: $!";
my $my_perl_variable = 'something';
print $pod <<EOF;
=head1 Imaginary Interpolation
This was defined previously: C<$my_perl_variable>
Of course, this would mean that you'd have to trigger the re-writing
process somehow ... if you were to give an interface for updating
whatever your variables were, you could regenerate the pod
afterwards. I personally couldn't see the advantage of doing this,
but I don't know what your full intentions are.

which has some more ideas.
http://www.perlmonks.org/?node_id=714673 also links to
which didn't contain much usefil information in my opinion.
(Or, maybe just replace, for example ---VERSION---, in
a program.pl-replace file with sed to make a program.pl file.
This has the advantage if you want to sync version numbers
on multiple programs and/or docs without making any file changes.
I used this type of thing for a project I did years ago
and it worked out prettty well.)
