Dangling Else

Why allowing IFs missing ELSE at all? Even Scheme forbids IFs without ELSE clause. Although retarded Common Lisp allows them, despite having WHEN and UNLESS.

Have a look at Nemerle language. Basically it has two macros: "if" and "when" that unfold themselves into pattern matching.

If you try use if without else clause, you'll be in world of pain.
