Function references are now equal if they refer to the same function, and if the parameter/return type adaptation, which happens when a reference is used where some function type is expected, is exactly the same. This includes the number of expected positional parameters (which can be affected by defaults/varargs), whether the coercion of vararg parameter to Array type happened, and whether the coercion of return type to Unit happened. #KT-37543 Fixed
