Ugh! I meant "The attached patch makes...".

"dump.cc" provides a single "dump_method()" method and a helper
class that implements the visitor interface over the model
elements. However, it is inconvenient to fetch a model_method *
every time you want to examine a portion of the AST and the
output would be unwieldy in some cases too.

My plan is to replace dump_method() with a more general
dump_tree(), but that means model_element being able to accept
a visitor and the visitor interface providing for a method
for a model_element, etc. Hence the need for this patch
before I can implement dump_tree().
