A modern programming language that makes developers happier.

I’m not sure if anyone else has ever needed an instance of `Random` that’s immutable, but here you go. <https://gist.github.com/cjbrooks12/cbe7e515ecfd75d63ca68db42da3a41b>

This is useful for programming with the MVI model, such as with <#CJLTWPH7S|compose> or when using the <https://github.com/copper-leaf/ballast|ballast MVI library>.  The default `Random` implementation is mutable internally, which can cause problems when your framework needs things to be immutable to work properly.

IMO keeping the `Random` interface is a mistake

There’s a lot of detail in the `Random` base class, plus a bunch of extension functions, that I didn’t want to copy. It could be confusing since it changes the behavior to be incompatible with the standard `Random`, but for my needs this is sufficient. And that’s why I just posted this as a gist rather than publishing it as a full library

This is what KMath Chain/Sampler API does: <https://github.com/mipt-npm/kmath/blob/master/kmath-stat/src/commonMain/kotlin/space/kscience/kmath/stat/Sampler.kt>
