As for extending lambda to allow multiple guards and/or multiple pattern

and will be lost at the beginning of a sequence of pattern

complicated pattern matches should be done using function equations.
I think I would like to allow a (single) guard on a lambda. for
assertion checking, I am a sucker for assertion checking and the more
lightweight the better when it comes to that sort of thing.
I like idea of a single guard on a lambda as well. I think it simplifies
the language (slightly) by eliminating a special case where patterns are
allowed but guards are not.
