Please include any other relevant details The error messages we get out of check-match can often be extremely misleading. Consider the above examples, where tests fail apparently claiming that 'a is not equal to 'a (when the read problem is that 'a is not an integer), and that 'a was expected but 1 was produced (when the real problem is that 1 is not a symbol).

I might take a stab at fixing this later if others can't do it faster than me.
