I havent got a solution but one avenue thats seems to be in the right field is
to exploit the difference between a function call and a declaration:

Sometype  func_or_value( Entity_to_test);

eg assume Entity_to_test is a type then func_or_value is a function, else
func_or_value is a variable.

Dont know if it helps though. The other slim hope is exploiting how e.g
std::for_each uses its last argument, but I dont quite know how that would help
if at all.
