I had in mind main perl executable but linked in such a way that it runs foo.pl seamlessly (not from any application, we were talking of a way to create EXEs out from perl scripts from the very start.)

suppose you have script foo.pl, which uses Bar:: and Fluffy:: XS extensions.
($^O equals to 'MSWin32' in my explanations)

You want to create foo.exe, much like PAR but with statical linking and w/o temporary unzips.

With an approach kept by me in mind (and by Ilya Zakharevich in mentioned link) you will result in:

• perl58s.lib <- static library, which is not against perl58.dll, but rather all the code inside it
• Bar.lib, Fluffy.lib <- same for extensions
• foo.zip <- to contain all text files with Perl scripts: foo.pl, and required perl core library
• perlmain.c from perl source distribution which contains RunPerl call, and link it against all mentioned libs
• concatenate resulting EXE with foo.zip like in Ilya's message

The resulting perl executable runs your foo.pl and w/o temporaries.
