EDIT: Please ignore this message, a good answer has been given above. You can alter the symbol table with *globs

The description does not really fit the title. In order to change a perl function in runtime, you would have to alter the symbol table. It can be done but it requires a lot of perl experience I think. Unless of course your function was defined as a reference to a function, in which case you can alter it as you would with any variable, which is trivial. Anyway I don't really see what you want to do.

It seems to me that what you really want is to just use 'eval':

package A;
sub Y { die "aargh" }
sub X {
   eval { Y };
   if ($@) { print "humm... Y failed..." }
   {
       print "ok, no error here";
   }
}
