Modern C++ in particular does a lot of similar, albeit not identical, codegen due to its extensive metaprogramming facilities. (C is, of course, dead simple.) I've never looked into it too much but anecdotally Rust does seem to generate significantly more code than C++ in cases where I would intuitively expect the codegen to be similar. For whatever reason, the "in theory" doesn't translate to "in practice" reliably.

I suspect this leaks into both compile-time and run-time costs.
