Extension point: Specify how to handle a parameter to argument count mismatch

<p>
The default is to throw an unrecoverable error. If allowed to continue, the matched
parameters are type checked and the invocation generated as specified. Most likely, the
emulator will crash while executing the invoked userop.

@param userop the userop being called
@param arguments the arguments being passed
