Rust: current RNLS has a problem with lacking semicolons

[thomasjm]

Unfortunately lines without semicolons are a normal part of evcxr. See the evcxr_jupyter_tour.ipynb notebook for examples.

Our current strategy of wrapping the rust in a big function isn't working; rust-analyzer doesn't like the missing semicolon and fails to parse after it.

Maybe ask in a rust-analyzer issue about it?

We might need to do fancier stuff in RNLS. Which will likely require a rust parser. The ones in Hackage don't look up to date:

This seems to be good now with the addition of replace_end_delimiter_with
