--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
This request makes sense to me as an enhancement to -Wunused-function. With
all the different forms of initialization in C++, it's not rare to accidentally
declare a function when a variable is intended, e.g., like so:
template <class T>
void f ()
{
T x (); // declares an external function
T y (T ()); // ditto
}
These mistakes are usually exposed when the symbol is used in a context where
an object is expected but extending -Wunused-function to diagnose locally
declared functions would help detect those that are not.
