does any language have a swap operator? like <-> or something? would be cool if kotlin had one. NVM just gonna use also

[karelpeeters]

Do you want to swap variables?

[karelpeeters]

Python has something like it: x, y = y, x

[Hullaballoonatic]

yeah, python has that, but kotlin does not support multiple declarations in a single line

[Hullaballoonatic]

without semicolons, but kotlin has x = y.also { y = x }

[Hullaballoonatic]

i just figure x <-> y is just as readable, and quicker, but i can understand why you wouldn't want to use type parameter brackets like that

[karelpeeters]

Yeah also is the standard solution for this I think.

[Hullaballoonatic]

there are quite a few features in other languages i wish we had in kotlin

[Hullaballoonatic]

mind letting me know your thoughts on each if i list them?

[karelpeeters]

Sure, thoughts are free simple smile
