Is it possible to do a negative infix operator?
I currently have this operator:
infix operator fun contains(option: Option): Boolean
I would like to be able to write both cases if (data contains MyOption) and if (data !contains MyOption)

[gian]

Use !in

[gian]

if (MyOption in data)

[jeggy]

I want to have custom logic

[gian]

when you override contains you are overriding in

[gian]

same as when you override plus and you can also use +

@Sergei Dubrov [JB] Exactly what I was looking for. No updates on that issue that last 2 years 😛

Why not this?

[jeggy]

ah, nice 👍
Didn't think that would work as it was a data class

[gian]

a in b is the same as b contains a
The "operator form" is in

Genius! Then I already had support for that. 😅

Thanks for the help
