I get similar concerns with functions that take multiple strings - how do I make sure I didn't swap the bucket with the key? I've seen enums used here, as well as "wrapper" classes.

In any case, to answer the question of "How does nobody(?) support this yet?", have you heard of https://frinklang.org/ ? It's not a useful tool for most codebases I work on but it's an interesting idea.
