Description:

I'm trying to get all public, but not static methods of a class using following 
code:

$methods = $class->getMethods(ReflectionMethod::IS_PUBLIC & ~ 
ReflectionMethod::IS_STATIC);

This however returns all public methods. It happens because of values of used 
constants:

ReflectionMethod::IS_PUBLIC - 256 (decimal) and 100000000 (binary)
ReflectionMethod::IS_STATIC - 1 (decimal) and 000000001 (binary)

This way binary subtraction doesn't really do a thing.

I suppose these constant values are designed to expand method range returned and 
not narrow down it instead.
