Is there any way to write this: https://glot.io/snippets/eya7pscezy without the

with

(not modifying the implementation of the

Weird

class) Not that I'd actually write this code

No, multiple receivers are not currently supported in Kotlin. There's been a fair amount of discussion about it, but I don't know if they ever will be.

What's the type of

withContext

in this example?

No,

withContext()

has a single receiver, but is defined within the scope of

Weird

, which creates another implicit receiver when you're not in the scope.

yep. so when you're not in the scope,

withContext

has two receivers, one implicit and one explicit?

Exactly

Is there any way to get a reference to that function? For normal member function, I can write

Weird::foo

to get a function, but this doesn't work for

withContext

No, that's something that bit me in the butt a while ago. Kotlin does not allow function references to functions with multiple receivers, and you can't even hack your way around it with

with

😞

<strike>ops, the

Weird::foo

only works for functions defined with

=

it seems</strike>

Weird::foo

will work with any function (not just expression functions), so long as it doesn't violate some constraints like the multiple receivers.

I have another question that's somewhat related to this: is the

@lparams

necessary in this code: https://github.com/Kotlin/anko/blob/84e3838327011996aee24fb25f682fc7c1f7779e/anko/library/generated/sdk25/src/Layouts.kt#L95-L103 or was it just placed there for clarity?

No, but it helps distinguish that you mean the

this : T

and not the

this : _AppWidgetHostView

.

ok, that's what I thought as well, thank you!
