I wonder if a subset of Rust would be a good candidate. It would certainly involve hardcoding the templates for some `unsafe` incantations into the compiler in order to treat Rust as remotely equivalent to a C target, which is beyond me, but _if_ it could be done the opportunity to reuse all of the Rust ecosystem would be killer. Heck, even generating only safe Rust with runtime overhead might be a fast enough of a runtime for an experiment with this.
