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.
Help!
