 - Add a new SublimeText syntax file for prog8, and also install this for bat: https://github.com/sharkdp/bat?tab=readme-ov-file#adding-new-syntaxes--language-definitions
 - callfar() should allow setting an argument in the X register as well?
-- AST weirdness: why is call(...) a normal FunctionCallStatement and not a BuiltinFunctionCall?  What does ror() produce for instance?
 - Can we support signed % (remainder) somehow?
 - Don't add "random" rts to %asm blocks but instead give a warning about it? (but this breaks existing behavior that others already depend on... command line switch? block directive?)
 - IR: implement missing operators in AssignmentGen  (array shifts etc)
