Re: [MacPerl] Unexpected behaviour with hashes

[robinmcf@altern.org]

Coding and stylistic points aside, the basic problem is the same -
for those of you that may have missed the original posting (real code can
 be supplied on demand):


 I'm using a hash to remove entries in another hash like this:

foreach $key(keys(%first_hash){
 	if exists ($second_hash{$key}){
 	delete $second_hash{$key};
 	}
 }

the problem is that even if I delete the $key I still get it and it's value
showing up later, prompting my question:

 Why?
