+- Port benchmarks from https://thred.github.io/c-bench-64/  to prog8 and see how it stacks up.
+- Since fixing the missing zp-var initialization, programs grew in size again because STZ's reappered. Can we add more intelligent (and correct!) optimizations to remove those STZs that might be redundant again?
 - in Identifier: use typedarray of strings instead of listOf? Other places?
 - Compilation speed: try to join multiple modifications in 1 result in the AST processors instead of returning it straight away every time
 - Compare output of some Oscar64 samples to what prog8 does for the equivalent code (see https://github.com/drmortalwombat/OscarTutorials/tree/main and https://github.com/drmortalwombat/oscar64/tree/main/samples)
