Thank you VERY much for that information. Nim providing the idetools looks like the best option for us, but implementing even one new language at the moment is very hard with the current resources available to use.
I'll put these in the backlog for future implementation plans but don't expect to see this implemented in the near future.
FYI, Komodo is built on the Mozilla framework and ActiveState has close ties to Mozilla (opensource mentality and ex-employees). A project manager there used to have my job ;) We'll have to reach out there about Rust and see what it's all about.
I'm going to keep reaching out to different places that support multiple languages regarding nim & rust (even though we do have Aporia, variety wouldn't be bad), it was worth a shot with the ActiveState team :P
