in thread source a file in Linux using perl script

I think the one drawback of re-executing yourself like that is that you lose Perl command line switches like -Ilib etc. ... There is Devel::PL_origargv, which gives you the original command line, but I'm not sure that I would want to go such an esoteric length when a shell script can do the same.
