A modern programming language that makes developers happier.

kotlinlang

I just discovered that the Byte and Short classes (and their unsigned counterparts) have no `shl` or `shr` infix functions. Is this intentional or not?

the operations don't exist in bytecode, only int and long shifts exist. Java automatically promotes byte/short values to int before all operations, and Kotlin does that for arithmetic like plus minus etc., but not shift. probably just not high priority, you can simply call `.toInt()` first

As a bonus, the reason it doesn't exist in Java, is because it doesn't exist in CPU architectures.

To my knowledge, `.toInt` and company are implemented as compiler intrinsics with a bit of magic, so they are more or less here so you know what you're doing, but have no performance impact at all

that's not 100% true on x86 due to compatibility going back to the 16-bit 8086/8088, but in practice none of those are faster
