In this sense I said that it's "specular": it's the same character.
In my case the character is different: ( in first group, ) in second group.

However, I'm surprised to see that the following works fine:

environment scheme_block delim `#\((\(*)` @{1} + ")" multiline nested begin
   environment scheme_block delim "(" ")" multiline nested begin
     include "url.lang"
   end
end

I'm surprised because @{1} refers to (, while ) should be used instead.
What I'm missing?

I think I'll send final files tonight or tomorrow. I'm quite satisfied now.

Thanks,
