This is OK and won't change. The ? feature does not handle compound
statements. It's a simple information feature, not a
compiler-within-a-compiler, and that is never going to change. It's a
limitation imposed by trying to keep the system simple and reliable.

This is certainly not a bad idea. I want to think a little more about ?
though, because I also want to incorporate the ability to search for things in
other ways (we already have the wildcards in SVN, but I'm interested in
keyword-type searches). So before cluttering more the ? character, we need to
decide how best to implement a good interactive information system. Scipy has
some facilities for that which we can steal, it's a matter of deciding on the
best desired behavior.
