As someone who&#x27;s been working on figuring out a way to transpile or interpret a powerful dynamic language to Lua, JavaScript, Python and Go, the really tough thing to do is non-local exits.  If you can solve that, I think that everything else is easy (well, a Simple Matter of Programming anyway).<p>It&#x27;s okay if your target language already supports non-local exits, particularly parameterised ones (although even that can be faked with a well-designed global), but if it doesn&#x27;t then it&#x27;s a pain (imagine how you&#x27;d do it in Go: every single function call will return an additional value, indicating if a non-local exit is intended).<p>Alternatively, imagine trying to transpile call&#x2F;cc to JavaScript…
