    In the end, I was able to implement these features:
    - Integer variables (single letter) and literals Variable assignment
    - Arithmetic with + - * % with precedence (unary + - only works at the beginning of an expression)
    - Comparisons with < > <= >= == (only one per expression)
    - Integer truthiness
    - if and else
    - while loops, including else blocks
    - for x in range(y) loops, including else blocks
    - Function definitions with no arguments
    - Function calls, even recursive
    - Indent-based blocks (without scope)
    - print with a single string literal or integer expression
