Actually I think that "T &" and "T const &" will suffice. The plain
reference will bind to anything except non-const temporaries.

BTW, in MSVC literals are const, so the plain reference works most of the
time.

The inability to write an argument that will take _anything_ while
preserving the type is pretty annoying - lambda function objects need it as
well.
