if you're not confining yourself to c-like languages, i like ocaml a lot too for a combination of fast dev time and good performance. has some cross-platform issues and multicore support is still lacking. if you have some familiarity with rust you should already be used to a lot of the ideas present in ocaml.

also, if you are already familiar with c#, there's f# which is essentially a port of ocaml to .net. won't improve the performance of c# but might improve the dev time a bit.

I have gone down the ocaml rabbit hole before. Likely, it was too early in my programming career and I got wrecked by the combination of novel concepts, poor docs, disjointed toolchain, and lack of ecosystem. I have, in more recent times, played with F# which is very nice.

A lot of these issues are now solved. OCaml universe now switched to Dune[1] as an uniform buildsystem, using ocamlformat[2] as an uniform formatting tool (succeeding over ocp-indent), Base[3] standard library aims to be the only one, a lot of legacy cruft was removed in recent compiler versions, along with improved error messages. Real World OCaml book[4] is now being modernized for the second edition. Recently even the design of documentation produced with odoc was improved and cleaned up a lot So it tries to catch up with more modern programming languages.
