I have two identical inline extension functions on

Collection<...>

. The only difference is one is on

Collection<String>

and the other is

Collection<Closeable>

. IntelliJ complains they have the same signature on JVM (because type erasure). Even though they are inline functions?

I asked a related question a while ago and didn’t quite get a satisfactory answer, though I suspect the culprit may be type inference ambiguity https://kotlinlang.slack.com/archives/C0922A726/p1542916167726000?thread_ts=1542916167.726000

Hmmm, it's weird how it works on Native but not on JVM. Isn't kotlin supposed to be somewhat consistent?

Inline functions are still callable from Java, so that doesn't remove limitations regarding their erased signature. You can use

@JvmName

to give one of them different name for JVM.

Oh, okay that'll do.
