The ELPA package wisi can help here (I'm the author).

This is the kind of thing that made move away from regexp to a true
parser for ada-mode, which eventually led to the current wisi package.

This definitely would be easier with a parser.

I did not try to answer these, since my real answer is "use wisi".

I don't see a grammar there, which is the first step in using wisi. Is
there a grammar available somewhere? or one for a similar language, that
would be easy to modify?
