This is not strictly relevant, but I remember that some years ago
(late 1970s?) there was an attempt to write a Logo interpreter
(including store manager and garbage collector) in Pascal and they
eventually had to give up because Pascal was such an impoverished
and unsuitable language. It's interesting that the reverse is
easier, even though many people think of Logo as a  "toy" language,
since it was designed for children.
