it is also very weird to see typechecking code in AST construction. is it possible to move these to the constant folder module?

meeting notes: approved but exact format tbd

note: as of c3e43d7b8a2e2236e236b9f23c3a8f9a96de349c, the number of TODOs has only gone up ``` (vyper) ~/vyper $ git grep TODO | wc 193 1749 16345 ```

note: `pos` was renamed to `source_pos` in dfbca3eea5118ebb7873979c2e122634b7c70c53. also the number of places where `source_pos` is added is very small, so this should be a much easier change now

also python ternaries

meeting notes: approved, use `await` keyword, wait until next "minor" release. (may reconsider the keyword in the future if actual async calls are a thing, e.g. sharded execution)

another even more exotic thought -- we could have all external fns be declared with `external def`, (and internal is the default visibility). this maps directly onto the python AsyncFunctionDef...

I think we should disallow `step` for now

the `start` and `end` args could have basically the same restrictions as `slice`, but maybe also allow negative end (so `xs[start:-1]` would be equivalent to `slice(xs, start, len(xs) - start...

another option is for interface methods to be camelCase, and local variables to be snake case
