In the meantime, however, I must continue to glean what I can from the current manual. Which brings me to the following interesting grammar entry: elaborated-type-specifier: key typedef-name key identifier I find this entirely confusing. The best guess I have is that this is just a plain goof-up. It doesn't seem likely that C++ really intends to allow: struct foo a,b,c; where "foo" has not been seen before. When I go back to section 8.2 in the reference manual to look for elucidation on the meaning of "key identifier", it refers me (indirectly) to the non-terminal "name-declaration". Is this production ("key identifier") completely extraneous and if not, what is it for? -Ron Burk
