Thanks. And what with the other question?

[adrianh]

Two questions:

• How many items are in the hash in the example you gave?
• Does keys actually returns a list in a scalar context?

:-)

[BUU]

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"
