As I mention in other email, getting the number of children is in general
impossible. Maybe, "has_children" flag would be more appropriate -- this
is somewhat more likely to be computable.

I am not sure it was you, but there was an IRC discussion about making
-stack-list-locals also print type of things -- can you describe exactly
how you gonna use that information, so that I have a chance to implement
that properly?

One important question is whether knowing a type of expression, without
knowing its address, is gonna help you very much.
