@haifenghuang When do you want to implement interface, public, private, protected keywords?

I ask because interface, public, private and protected keywords available, but they do not work.

When designing the magpie language, I want the language to support these. But it's not that easy. If I implement these, the source code must be redesigned. That's a lot of work, so I have no plan to implement these, at least in the near future.
