Greetings,

Please find attached a small wrapper function that could be useful as a
replacement for forward<>() which uses explicit type specification (for
some reason), shorter to type and can be used as perfect forwarding for
virtual functions as well, not only with template functions. You can use
it for universal parameter types as well.

The attached executable will output the following:

1) classic foo(i):
void foo(T &&) [T = int &]
void bar(int &)

2) classic foo(9):
void foo(T &&) [T = int]
void bar(int &&)

3) classic a.foo(i): error

4) classic a.foo(9):
virtual void A::foo(int &&)
T &&pass(T &) [T = int]
void bar(int &&)

5) suggested a.foo(pass(i)):
T &&pass(T &) [T = int]
virtual void A::foo(int &&)
T &&pass(T &) [T = int]
void bar(int &&)

6) suggested a.foo(pass(9)):
T &&pass(T &&) [T = int]
virtual void A::foo(int &&)
T &&pass(T &) [T = int]
void bar(int &&)

Regards,
