Nimony and Julia are a couple "up-and-coming" languages to really be looking out for over the next few years, as they are both really coming into genuine maturity.
These languages would be more comparable to Crystal if they were ready to use for applications development.
Nimony is more-or-less a pre-production Nim 3. It has an extra pinch of distinction in mature functionality, polish, ergonomics, and stability. Nimony has some way to go before it is production ready.
Julia is a fast dynamic language that could start working on maturing solid static compilation for applications development, which I think would significantly bolster the language. Julia already has a set of features that most static languages would be envious of.
