Two questions: How many items are in the hash in the example you gave? Does `keys` actually returns a list in a scalar context? :-)	[reply] [d/l]

keys in scalar context returns the number of elements in the resulting list. Whether this is magic in the keys function, or it's returning an "array" instead of a "list", I have no idea. `>perl -e"%x=qw/foo bar 1 2 3 4 baz bar/; print scalar keys %x" 4` [download]	[reply] [d/l]
