rest function?

jarwulf has asked for the wisdom of the Perl Monks concerning the following question:

Does anybody know of a rest function in perl? $return_line = rest($short_module, $peakapex); I'm not exactly sure what it does. The only includes the pl file has are use File::Spec;. I tried to google but the only thing I get is some sort of 'RESTFUL' framework which doesn't look like its the same thing.

use Devel::Trace and/or B::Xref and figure out where sub rest is defined	[reply]

Check the _full_ code of your source. Isn't there any XS/C code around it, so that some C is integrated in your Perl ? Or the other way round, your Perl is integrated in some C app ?	[reply]

You have not provided any context or background where you got that line from. Have you considered that this is a typo? Like reset, restore, test or similar...	[reply]

includes Since you use this term, just want to make certain that you're checking both for `use` and `require` and that you know that these can appear practically anywhere in the file. If you find no other sources, maybe `rest` simply isn't defined at all. For example: `perl -e 'if(0) { $return_line = rest($short_module, $peakapex); } else { print "foo\n"; }'` will run without error (ignoring `strict` and `warnings` for the moment). Probably not so obvious in your program but you can check for this situation with a nearby print statement or, of course, a proper debugger. If even this doesn't explain it, the definition of rest must be hidden in you file somehow.	[reply] [d/l] [select]
