Thanks for checking in the stuff. However, I am really sorry, but my code contains a bug! Example: "{Foo:=-0.9,...}" Problem: "lex" parses ":=-" as one lexeme

One can reasonably argue that this is actually a bug in show, not read. It can be fixed by adding parens, or spaces, to the show. (I'm inclined towards spaces myself.) Regards, Malcolm
