This will be a list of languages that I've tried to date, I usually make web stuff so I'll be looking at these from the perspective of someone trying to write websites:
rust - very mechanical, compilation times aren't bad, especially with incremental compilation. The language however is huge and too big for me to be happy. There is so much to know which depending on my mood is a good or bad thing. The frameworks available all feel cumbersome because of the language and the frameworks themselves.
zig - A C replacement but its not mature enough yet for a web framework.
nim - Whitespace is important! I think this is something that really pushes me away from it. It has some cool ideas like case not mattering or dashes and underscores being interchangeable with camelcase.
crystal - Looks interesting, still need to give it a shot but having issues with using the web framework with an old version off ssl due to centos 7.
