Regarding a more approachable compiler, better testing and less rough edges around language features: there is the recent [NimSkull](https://github.com/nim-works/nimskull) project (basically a hard-fork of Nim), which - among other things - aims for these things.
In the future, maybe some of their efforts can be integrated back into Nim? PS: I hope it's okay to mention NimSkull here on the forum? As far as I can tell, it hasn't been mentioned here yet. A cursory search also yielded no results on what the official stance on that project is
