-----Original Message----- From: Jason Foster [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 19, 2004 2:51 PM To: [EMAIL PROTECTED] Subject: Dynamically creating a hash for keys() Can anyone help me to understand why this code refuses to compile? Even better, can anyone help fix it :) %hash = qw( fred filntstone barney rubble tom delong ); print( keys( reverse( %hash ) ) ); The error message... Type of arg 1 to keys must be hash (not reverse) at ./killme.pl line 4, near ") ) " ... was pretty confusing since it implies that "reverse" is a type?! I tried making an anonymous hash as follows... print( keys( %{ reverse( %hash ) } ) ); ... but got no results at all.
