Yeah I think that’s right.  I’ll just note though that behaviour when
passing too many or too few arguments is still an open issue (although
it’s more likely that the ‘too many’ case will change than the ‘too few’
case).

OTOH, passing in undefined explicitly as the second argument would have
it converted to the string "undefined".
