I was keen to read about this lang bc it came from m$, but this looks like it needs some work: I'd highly suggest changing "var" and "var!" definitions.

From your doc:

>var z = 5;

z = y; //error z is not updatable

"var" is shorthand for 'variable' as you're no doubt aware, so use "const", or use something else altogether to indicate a var.

I stopped reading after coming across your unintuitive "var!" syntax. Let an apple be an apple and an orange an orange.
