Hi,
I have been reading the improvement that will be made to C++0x, and
one of this is "A Proposal to Add an Rvalue Reference to the C++
Language" , which will add a double &, for example:

int someFunction(in t && a){ ...

the reason is to allow to change temporaries passed to functions.

My proposal is to change '&&' for 'mutable &'

My bet is that it's not going to happen. Too late. Many compilers
have already implemented the && syntax. Besides, would you allow
the keyword 'mutable' to be used in the context of declaring a pointer
to something? What if you want to declare a mutable data member that
is itself an r-value reference? "mutable mutable"?
