Is there a way to use select (or some other similar mechanism) to select for messages on an arbitrary set of Channels not known at compile time (provided the channels have the same message type)?

what's wrong with using

select

?

Ah, I hadn't found any docs which did something like that, wasn't sure if calling onReceive in a loop in a select block would do what I want

there's no magic language feature, it's just library code , so I presume it will work because it's just like listing individually

The following works as well

val receivingA: SelectClause1<Foo> = channel.onReceive
select { // this: SelectBuilder<Foo>
    receivingA { it }
}

The key thing is that you

invoke

on the SelectClause returned by the

onReceive

property from inside of the

SelectBuilder

context
