FlowCollector.emitAll

[fvasco]

This is a trivial extension with the only focus on readability.
I tried to implement a trivial plus (a.k.a. concat) operator:

operator fun <T> Flow<T>.plus(other: Flow<T>): Flow<T> = flow {
    this@plus.collect(this)
    other.collect(this)
}

Is emitAll more readable?

operator fun <T> Flow<T>.plus(other: Flow<T>): Flow<T> = flow {
    emitAll(this@plus)
    emitAll(other)
}

public suspend inline fun <T> FlowCollector<T>.emitAll(other: Flow<T>) {
    other.collect(this)
}

public suspend inline fun <T> FlowCollector<T>.emitAll(values: Iterable<T>) {
    for (value in values) emit(value)
}
