So would I, but I'm afraid I can't turn lead to gold. ;)

If both syntaxes were realizable, I would certainly consider it.  As it 
stands, someone considerably more clever than I would have to make my 
original proposal work. :(  It's not just VC6 that wouldn't like it. 
I'm afraid there might not be any legal way to do what I suggested in 
C++.  In particular, foo<n> can only name a type, not an object.  And as 
far as I know, you can't call the subscript operator on a type.  I guess 
that's what happens when you talk first and think later. ;)
