These should be on a separate class such as
class _FunctionImpl implements Function {
  bool operator ==(other) ...
  int get hashCode ...
}

so that other user-defined classes that extend Function do not inherit these
methods as this would break the assumption that the receiver is a Closure within
the VM.

Done.
