my most desired features by likelihood they'll ever be added: * possible: default parameter types * unlikely: list literals.... * impossible: unbounded-range w/ operator

KEEP for literals: https://github.com/BenLeggiero/KEEP/blob/collection-literals/proposals/collection-literals.md

I just hope kotlin won't go into a symbolic direction. I don't mind writing words, as they say

you write it once, read hundreds of time

. list literals would not bother me (but I really don't care), as long as kotlin stops there 🙂
