is there an idiomatic way to get multiple mins if they are

==

?

If they are equal, why would you need multiple?

@Ruckus if I am using

minBy{...}

it might be nice since the contents of the actual object might be different

I can't think of a way to do that logically in one step. You'd need to do something like:

val thing = things.minBy { it.value}
val found = things.filter { it.value = thing.value }

yeah... inefficient but clean

Maybe, but I can't think of a more performant way to do it in one pass. You'd have to maintain a list of all matching found records as you go, throwing the list out every time a smaller value is found. You'd have to benchmark it, but I could see that kind of overhead being comparable to two iterations.

perhaps you're right

Ignoring performance, it could be useful if the thing you're iterating over doesn't handle multiple iterations.
