Like modularize it more so they can have a subset working on Java and make the compiler faster / better / more tooling support.
That would've been better with yet another JVM language. The community is splitting and splitting and still most people think in the same niche, but they always use their different syntax.
I mean kotlin does a lot of things like scala but still tries to be his own language and doesn't use as much fp as scala does. it also uses 'it' instead of '_' not sure why they came to 'it' also the data classes so much work around stuff, thats just aweful.
Hopefully Java will get more functional so that we don't get a too fragmented community.
P.S.: Yes everything has it's place i just dislike whats happening in the it, so that everybody wants to do his own thing instead of working together.
