[2.2]Programmable AI via scripting

[Som1Lse]

This is cool. Kinda makes me want to create (or at least start) a mod using it.

Questions:
Is there a way to remove/hide the terminal. (haven't experimented with this too much, so it might already be implemented, and I just haven't found it)

Also, does defining functions within the script cause performance issues, as they are defined every times the script is run?
For example: (obviously the "func" function is quite useless)

C-Code: def func(){ print("test"); }   func(); func(); func();   return 0;

Would it be better to simply write print("test") thrice?

And lastly, can you make global variables that are shared among scripts, and variables that keep their value from the previous execution?

(If some of these aren't implemented, I would love to see them implemented)
