Seems extremely interesting. But in passing it may be worthwile to remind a cheap alternative that would yield the absolute maximum of portability: editor macros or templates. For example you may create a template like thus

#!/usr/bin/perl

use strict;
use warnings;



__END__

If you know that you're using a certain module, say File::Find, quite often, then you can include it with a cmt in said template:

# use File::Find;

and you may create a suitable macro for inserting subs: I don't have any, but with my editor (jed]) it would be easy to create one that would ask me for a name, say foo and create this code for me:

sub foo {
    my $var=shift;

}

positioning the cursor on the empty line, or on $var, to allow me to switch to a more sensible var name.
