[antlr-interest] Parsing expressions inside a double quoted string?

[Rodrigo B. de Oliveira]

Oh, I see.

I didn't think it was possible... I've just went through all the docs and
it's clear how it works now, thanks.

I still haven't been able to figure it all out. For a start I want the
lexers to transform this:

"Hello ${foo}, ${2 + 2}"

into this:

"Hello" + (foo) + ", " + (2 + 2)

I'll give it some thought again later tonite.

Thanks again,
Rodrigo
