#pragma message "using Ivan J. Johnson's ARRAY_SIZE2"
// Works on older compilers, even Visual C++ 6....
// Created by Ivan J. Johnson, March 06, 2007
// See http://drdobbs.com/cpp/197800525?pgno=1
//
// Pseudocode:
// if x is not an array
// issue a compile-time error
// else
// use the traditional (non-typesafe) C99 COUNTOF expression
//
// If the argument is any of:
// object of class type, such as an std::vector
// floating-point type
// function pointer
// pointer-to-member
// then the first reinterpret_cast<> is not legal (compiler error)
//
// The type for check1 is chosen and named to help understand
// the cause of the error, because the class name is likely to
// appear in the compiler error message.
//
// If check1 succeeds, then the argument must be one of:
// an integral type
// an enumerated type
// a pointer to an object
// an array
//
// Check2 expands approximately to sizeof(check_type(x, &x)),
// where check_type is an overloaded function.
// Because this is purely a compile-time computation,
// the function is never really called or even implemented,
// but it lets the compiler apply overload resolution,
// which allows further type discrimination.
// There are three possibilities to consider:
// x is an integral type or enumerated type.
// In this case, neither of the two function overloads
// is a match, resulting in a compiler error.
// x is a pointer to an object.
// In this case, the first argument to check_type()
// is a pointer and the second one is a pointer-to-pointer.
// The best function match is the first overload of check_type,
// the one that returns an incomplete type (Is_pointer).
// However, because Is_pointer is an incomplete type,
// sizeof(Is_pointer) is not a valid expression,
// resulting in a compiler error.
// x is an array.
// In this case, the first argument to check_type()
// is an array and the second is a pointer-to-array.
// A pointer-to-array is *NOT* convertible to a
// pointer-to-pointer, so the first overload of
// check_type() is not a match.
// However, an array IS convertible to a pointer,
// and a pointer-to-array already is a pointer.
// Any pointer is convertible to a void*,
// so the second function overload is a match.
// That overload returns a complete type (Is_array).
// Because it's a complete type,
// sizeof(Is_array) is a valid expression.
// Thus, the compiler has EXCLUDED every possible type
// except arrays via compilation errors before reaching
// the third line.
// Moreover, check1 and check2 are reduced to the value zero,
// while the third line is the old type-unsafe C-style macro,
// now made entirely type-safe.
//
// Additional benefits:
// The result is itself constexpr
//
