-Wall only complains about shadow bindings, defined but not used, and no type signature.  But no unmatched patterns.

Yes it does: one of the options it brings in is -fwarn-incomplete-patterns which tells you if you've missed a pattern match.

Sorry, I should have been more clear. When I run the program with -Wall, the only warnings I get are shadow bindings, values defined by not used, and a couple values without a type signature. But I don't get any warnings about either unmatched patterns or overlapping patterns. -Tom
