in reply to change perl function in runtime

You need *globs to manipulate symbol table entries like package functions! ( see perlmod and perlsub)

Something like this should do

{ package A; local *x = sub { die "aaa" }; #run tests ... } # &x reset after leaving block

if you want to explicitly reset &x try to store the old coderef before.

$old_coderef = \&x; # run tests ... # do what you want ... # (but think about the omen ;-) *x = $old_coderef;

Cheers Rolf

    It works very well. This is real perl alchemy :-)
