A modern programming language that makes developers happier.

kotlinlang

yeah - it's very nully as it stands. Those are great ideas, thanks, I'll have a play tomorrow.

That's fine, it can pass a function to the other of `{ it.random.nextDouble() &lt; nullChange }`

I've actually done both, I'm close to being done - just putting some docs/kdoc, will submit a PR tonight, happily remove either version though. In our codebase we use orNull() a lot with the old kotlintest to replicate the input from another system being null, and I can see us using (`orNull(0.25)`  a lot, but that's not to say that version of the function needs to exist in Kotest, it'd happily live in our code)

Just pushed to the branch/ PR: <https://github.com/kotest/kotest/pull/1414>
