Overview

Build the C++ pointer-to-function expression Rice needs to bind a method or free function. Most compilers can resolve ‘&Foo::bar` against the surrounding template-deduced signature even when `bar` is overloaded, but MSVC cannot, so when the name refers to an overload set we wrap the address in a `static_cast` whose target type is the signature:

non-overloaded:  &Foo::bar
overloaded MSVC: static_cast<void(int, float)>(&Foo::bar)

.format(cursor, qualified_name, signature) ⇒ Object
