If identifier has never been assigned, assign it in current scope
If it has been assigned, reassign it at that scope to value
Needs a global assignment and local assignment, maybe rename = to set or something
This changes how code is executed a bit, code from the stack is popped to an execution stack before.
This makes global executed functions and anonymous ones identical.
Not super well tested as always :]
Not very well tested, needs a better public API, not integrated with Minetest, ...
This is WAY bigger than a commit should be.
The next stages will be:
- unit tests
- API (allows it to be more than just a language for this project)
- integration with Minetest
