Typedeffing "auto"

[Johannes Schaub (litb)]

I just figured that it's forbidden to "typedef auto foo_type;".

Can you think of any use-case for it? I imagine a C++0x program could
typedef "auto" to a different name in C++0x mode, and use a type-erasure
class in C++03 mode for storing some expression of an unknown type localy.

Would there be any practical difference to:

#define foo_type auto

?

Respect for scope and access control.
