If I'm the only one who wants this, then it won't be a priority for him
- and it shouldn't be. However if enough people want it, maybe he'll do it.

All I'm after is the ability to use a shebang line that will always
point to the currently selected version of Perl that I've chosen by the
perlbrew switch command. If I use #!/usr/bin/env perl, my system Perl gets
used - no matter what perlbrew is set to. If I hard-code a perlbrew installed
version of Perl, then that particular version gets used. I'd like to be able
to use some generic shebang line, something like
#!~/perl5/perlbrew/bin/current, and then that script would use the currently
selected version of Perl. Now when I change versions with perlbrew, I don't
have to change any shebang line.

What I'm asking for would not interfere with any system files.

Nope. Let's use my shopping cart script as an example. Running MAMP
on my Mac, and using a browser to access the script, I want to select different
versions of Perl to test it with, using perlbrew, to make sure it will work no
matter what version of Perl is running.
I referenced this page yesterday where someone asked pretty much the
same thing last year:
