Well, the last I recall ANTLR didn't handle nested {}s anyway,
meaning that if you wanted to use them you had to use \{ and
\}. So that would look different, and wouldn't be a problem.
Or am I thinking of nested []s for parameters? Or possibly I'm
just going mad :)
Anyway, another option could be to use a magic prefix
symbol. @{...} springs to mind for some reason, though I don't
know why ;) {Maybe it's from literal strings in C#.]
