[kw-pm] Perlbot's ability to load/release/reload modules on the fly

[Justin Wheeler]

This is probably an oversimplified answer.  Feel free to slap me if you
like.

Sounds like it's simply an eval.

open (code, "blah.mod");
@code = <code>;
close code;
$code = join("\n", @code);
eval($code);

open (code, "blah2.mod");
@code = <code>;
close code;
$code = join("\n", @);
eval($code);

... there's always more than one way to do it... but.. I would imagine
it's something along these lines.. (not that simple, of course.).. but you
get the idea.

Justin Wheeler
