We can currently fake boolean globals by using 0 and 1, but is there a reason that we can't just have boolean globals?
If you take the INT output of a boolean instance variable, it's a 0/1 depending on false/true. I think having global variables to have the option of "boolean" makes sense for display purposes in the editor.
I think it's been posted about before, and I believe it's on Ashley's todo list.
