at this point only binary operators are implemented, unary are yet
to do.
getters and setters for native classes implemented with the names
@getter, and @setter (however the names or arity aren't validated
at the moment TODO:)
this is a part of the class implementation. In this commit classes
and instances type were completely cleaned and prepared for a new
implementation. Native class registering mechanism were fully refactored
and made it much simpler.
now it's easier to re-use cli modules into another hosting
application and a little python script have added to generate
native api to support native extension library.
