Crystal wants very badly to displace ruby, in order to leverage the network of developers and generate more and more attention. It's a smart decision on their part.
As such, crystal doesn't seem to have munch interest in low-level nitty gritty. "we aren't trying to be C" is a common comment amongst contributors.
For game dev, (why I'm bothering with rust) it's too big a turn off to ignore.
For web dev, I suspect crystal will ultimately find some success. Lucky framework has some REALLY cool features that rails hackers are going to discover eventually.
Unless ruby 3 drops a type system bomb and finds a 10x perf speedup, the continuing progress crystal is making will consume the ruby ecosystem.
Congrats on another successful release! Still no exhausting matched, no parallelism, and the spectre of type system changes in the future still looms, but aside from those things, looking good!
And windows support. But I personally don't mind windows support being missing. Fuck 'em. Continuing to settle for windows with alternative implementations and things like Wine only gives windows more power as an antihero. Let them be forced to adopt a Linux kernel, no compromise.
