Thanks, ysth!

Oops, ya.

That's what I thought, too. The problem really is that at import time, I'm trying to dig into functions of the caller that haven't been compiled into the symbol table at the time. In other words, the list of functions passed to the import represent functions the caller wants me to change, yet because they're called at compile-execution time, too, nothings there. The only function that's assigned at the time was BEGIN, so I gave it a try. With the re-require of the calling package, the functions get assigned to the symbol table and I can change them at my will anytime after that. (did that confuse things more?

 > > Have you tried a glob assignment?
I did, and although that looses the warning - I hit the problem I mention earlier. Essentially, I'm trying to add some aspect-ish slicing to any calling package, where to effectively do so, I need to have the functions already defined - does that make sense? Where if I simply use a GLOB assignment, I overwrite the entire function; which isn't really my goal.

'Caller' example 
package Caller;

use strict;
use warnings;

#
# The idea being that I want MyPackage to do something
# with 'use_this_function'.  Because I can't guarentee the
# function will be defined at the point of import, I'm trying
# to force the compilation of the module in order to get
# the assignment in the symbol table so I can change it appropriately
# (I use that word lightly here)
#
use MyPackage qw( use_this_function ); # From earlier example

function dont_use_this_function {
  return;
}

function use_this_function {
  return;
}
