[TxMt] Request: Matching scopes.

I am doing a bit of Scheme-programming and have spent a few hours
trying to make TM understand Scheme syntax in a feasible way. Syntax
coloring is no problem since I can do recursive patterns (via
includes). However, I cannot find a solution to indentation. What I
have is a rule that creates a new scope called "expression.scheme"
for each nested expression, for example:
(if (= a b)
(+ c 1)
(+ d 2))
where 'c' (as well as 'a', 'b' and 'd') has the scope "source.scheme
So, this is my suggestion:
How about making the pattern matching engine scope-aware, so that I
can match beginning and end of scope? I believe having that would
make it a breeze to get indentation to work okay with Scheme, just
make a preference tied to scope "expression.scheme" and tell it to
increase indentation at the beginning ot the scope and decrease it at
the end. Each nested scope would then automatically add an
indentation-level, which is what is needed to indent right. (And
while I'm at it, to be able to set folding at the beginning and end
of scopes would also be awesome... :))
I don't think it is possible to do proper indentation for Scheme
without some new feature, but I could be wrong. Anyone have an
alternate solution? Please tell me.
Anyway, thanks for an outstanding product!
