I think you'll agree that concerns about code size, speed, and dependency on 
other libraries are in general reasonable. It would help a lot, if instead of 
one person expressing such concerns and another person stating that there's 
no need to worry, you'll provide us with a table of grammars and code sizes 
on various compilers.

Again, I'd like to see numbers. After bcc has converted
        
        tuple<int, int> t(1, 2)

in 40 assembly instructions, I don't believe much in optimization 
capabilities of compilers.
