An incompetent coder:

I actually do kinda a lot. It is kinda useful for adding 
declarations with mixed in names (the whole declaration must be 
mixed in even if the only unique part is the name), or the first 
instance there is to version out features where the compiler's 
parser worked (I maintain compatibility with 2+ year old 
compilers too and if the parser changes, version alone will not 
work).

I could probably live with that too, but the status quo is pretty 
useful as-is.
