Exception thrown when parsing malformed match statement #108

Open kjcjohnson opened 1 year ago

kjcjohnson commented 1 year ago

Reported by @panda2134: a gross error message parsing an (invalid) match statement:

    (! (match t0 (
            (($Prod1 v) ...)
            (($Prod2 e1 e2) ...)
            (($Prod3 v t e)) ...   ; <--- note misplaced close paren here
        )) :input (...) :output (...))

This gives:

Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.InvalidOperationException: Too many terms to match pattern.

As usual, absolutely no helpful information here 🙃
