I guess you're the yin to my yang, because I've got a compiler written in C that doesn't use any global variables at all: https://github.com/srh/kit/tree/master/phase1

It wasn't really implemented for performance, and maybe the language is more complicated -- no doubt it's a lot slower. On the other hand, I can look at any function and see what its inputs and outputs are.

My compiler isn't optimized for performance, either! I didn't do much other than expanding a linear symbol search into a few more lines doing binary symbol search. And I've got string interning (hashing).

I've mostly optimized for clean "mathematical" data structures - basically a bunch of global arrays. This approach is grounded on the realization that arrays are just materialized functions, and in fact they are often the better, clearer, and more maintainable functions. If you can represent the domain as consecutive integer values, of course. So I've designed my datastructures around that. It's great for modularity as well, since you can use multiple parallel arrays to associate diverse types of data.

But anyway, your language looks impressive I must say.
