Is anyone aware of tooling or languages in existence that allow for maintaining codebases with multiple supported languages? I'm imagining something similar to a git hook that performs translation at an AST level, where library can provide a "strings database" that maps it's public members into arbitrarily many languages. I could imagine for multinational companies, it might even be worth hiring dedicated translators to maintain manual translations as part of such a system, although it would definitely be desireable for it to fall back to machine translation. That way, anyone could check out a version of the code that's localized to their native language, including language primitives, standard library calls, variable names, comments, etc. without fracturing the whole library ecosystem by language boundaries.
