Replacing a function call `foo(bar, baz)` with just `foo()` by bringing `bar` and `baz` into context is not meaningfully better in any way. I'd even argue it reduces the readability of the code due to implicit receivers.
These features encourage chasing after diminishing marginal return in aesthetics and conciseness, taking up developer time that would be spent better elsewhere. They are also needlessly complicating the language and IMO don't carry their weight.
However, I do feel like Kotlin has too many features as a language.
What I'd really like to see is a typed functional language with a minimal feature set, and that's how I use Kotlin. That said, using a language subset within a lang that has a large surface area tends to fall down over time. Team discipline can only go so far.
