It’s actually been brought up a few times in the past, but yeah, it is quite an undertaking.

I've just checked out the Oniguruma sources. I guess that adding new assertion types is probably beyond the scope of its pluggable syntax mechanism. And I imagine that's just the first, small hurdle...

So, more prosaically: support for folding where a language supports a mix of recursive and non-recursive syntaxes please :)
