And if I wanted to make 'for' into a valid variable name, or change the tokens for specifying numbers, for example, how would I go about doing that?

  Easily. The macro gets handed the ast of the input. It can interpret it however it wants. There are no reserved words or anything like that. Much of nim is implemented as macros, just like most lisps

    The lisp macros run before the AST exists.
