A literal string type for Python

A literal string type for Python

To a large extent, though, these sound like the same problem as unsafe in Rust; sure, I can wrap all sorts of crawling horrors in unsafe, and have a Safe Rust API on top so that when you look at my crate's documentation, it's not obvious that I've done this.

And similar to Unsafe Rust, the answer is tool-assisted review of code you're planning to use that highlights the areas of code that need extra attention - just as a Rust-aware review system calls out unsafe wherever it appears for extra human attention, so a Python-aware review system needs to call out manipulation of LiteralString that results in a LiteralString typed output for extra human attention.
