A modern programming language that makes developers happier.

kotlinlang

Is it still the case that the bytecode viewer in IDEA doesn’t properly reflect the final Java class output?
Simple things like `(0..10).forEach { … }` cause an `IntRange` and an iterator to be allocated.
If I recall correctly calls like that are supposed to be optimized.

It's unstable feature with many restrictions. I usually run `javap -v` for generated classes, and it works OK

However, it would be nice if Kotlin had a decompiler at least for subset of code emitted by backend :(
