I'd vote for "$" - that's the first one that came to my mind. What I=20
like about it is that it's a plain ascii character (no danger of messing =

things up with UTF8 - which "=A7" does for example).

 From (briefly) looking at the evaluator, I guess it should also be=20
possible to use more than one character as a delimiter, without things=20
getting _too_ complicated (so, "::" or "->" should be doable). But I=20
don't see the need to do the extra work, which is why I'd vote for "$".

If you want to get _really_ fancy (or if I lose my job and have tons of=20
time to spare), one could also extend the evaluator to do a more=20
sophisticated scanning/parsing (by writing up a grammar and feeding that =

to lex and yacc), but I guess none of us has that much time to spare=20
(especially for little or no additional benefit).

Well, it wouldn't really change anything - since then, we'd be looking=20
for a new separator for concatenation (and there's no "natural" one,=20
unless you think in Basic, where "+" or "&" are used for concatenation - =

not terribly elegant, especially since it's already used anyway).
