Does

Flow

have a corresponding

select

clause, and if it doesn't, is it planned ?

what would you want to

select

on? I suppose

single

might make sense, but it's still an extension based on

collect

, so

collect

would need to be selectable, but

collect

doesn't really seem like a good idea for it

I'd like to receive simultaneously from the

ReceiveChannel

of an

actor

and the items emitted by a

Flow

. Should I convert my

Flow

to a

ReceiveChannel

with

Flow.produceIn

in order to use the

onReceive

clause ?

that sounds like a better option

I think

select

in general doesn't make sense for Flow -- it's a cold stream, so it won't start until you consume it, but you won't start consuming it until you call

collect

, and if you

select

, you're technically not consuming it, so it will never be started

Another option is convert channel yo Flow and use combineLatest operator
