RE: Nested guards?

Interesting, I didn't know that.

But (a) Clean guards don't bind, and pattern guards that bind was where this thread started.   And (b) the
Clean manual says: "To ensure that at least one of the alternatives of a nested guard will be successful, a
nested guarded alternative must always have a 'default case' as last alternative".  That's a pity.  The
main point about guards is that failure means "go on to the next equation", a semantics that they could have
chosen I guess.
