Fair point. Or combining them both: Writing a language interpreter in Python as if you were writing it in C, and then complaining that it is slow, is only going to elicit "well uhh yes?" responses. Languages like NetRexx (and, I think, Jython, although I can't find any definitive and current answers) are slightly different from their "parent" languages, because they make good use of their implementation languages' features. This Prolog interpreter might not even need to be different in functionality, but its implementation would be different, and it could take advantage of the underlying garbage collection.
