misterperl has asked for the wisdom of the Perl Monks concerning the following question:
Things that make u go HUH..
I'm trying something like:
($cgi is a hashref, @KEYS = keys %$cgi)
If I try:
die join ',',@$cgi{@KEYS}
I get a list of values from the hash, as expected. All is good.
BUT, if I try
my @vals = delete @$cgi{@KEYS}
I get an array of length @KEYS, each element empty ( eq ''), even though the array has values I can see in the die? delete should return an array of the values from the deleted slice?
I humbly seek counsel. I don't get it.
PS I should have mentioned - YES, the hash elements are indeed deleted... I just cant get the vals back....
