"The language is rapidly converging on an ownership model similar to rust " Nice. Do you have more resources on that? Also, does Nim have a WASM target?

Here are some handy links (for me) that might help you out too: https://nim-lang.org/blog/2020/10/15/introduction-to-arc-orc-in-nim.html https://nim-lang.org/blog/2020/10/15/introduction-to-arc-orc... https://www.youtube.com/watch?v=aUJcYTnPWCg https://www.youtube.com/watch?v=aUJcYTnPWCg https://github.com/stisa/nwasm https://github.com/stisa/nwasm You can also go an Emscripten route: https://hookrace.net/blog/porting-nes-go-nim/ https://hookrace.net/blog/porting-nes-go-nim/

Nim is apparently getting support for owned pointers [1]. There's a proposal [2]. The proposal PR has since been closed, but it's apparently still being worked on.

  I had played with and really liked "owned". However there was design issues with it and that feature was forgotten.

  Most of those semantics are now tracked automatically without needing annotation in arc/orc.

Re: WASM -- https://github.com/nikki93/ng-public https://github.com/nikki93/ng-public -- Public repo for a game side project I've been working on that does Nim -> C/C++ -> WASM (native desktop also works, iOS probably works (have used the same build system for C++ iOS before) and Android can be made to work). One of the modules involved wraps entt which is a template-heavy C++ library and not many languages can actually wrap with just a cdecl-y ffi layer. Re: borrow checking: https://nim-lang.org/docs/manual_experimental.html#view-types https://nim-lang.org/docs/manual_experimental.html#view-type... It's still pretty early and also IME the mix of arc (which is determinstic) with manually managed memory (esp. through some data structure that manages entity data like entt) has been pretty nice.
