Re: change perl function in runtime

[LanX]

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;

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