Does 
Any
not work for any generic? I have code that's 
Expected : <http://Request.POST|Request.POST><Any, O>
Actual: <http://Request.POST|Request.POST><I, O>
and that's causing me some issues

I believe you wan to use 
T
instead. I'll check into that.

The letters shouldn't matter for generics? I have a half dozen different ones

You're right. Letters don't matter. I misunderstood your issue.
I believe the problem is that 
Any
allows for more than one type where a generic of type 
T
or 
I
or whatever you choose constrains it to any one type.

Isn't 
Any
the equivilent to Java's 
Object
Where everything extends it?
So generic 
I
should be a subclass of it
Even explicitly putting 
I : Any
it's failing

Well that I think is the issue. 
I != Any
because an array of type 
I
would be an array of one type explicitly. i.e. 
arrayOf<String>("a","b","c")
where 
Any
could be 
arrayOf<Any>(1, "Blue", SomeObject, ...)

That would still compile though. 
I
is a subclass of 
Any
so it should work

Sorry, I'm looking at it backwards.
You're passing 
I
into an 
Any
parameter not 
Any
to an 
I
parameter

Yes

Interesting.
Does it give you any specific error response?
aside from the 
expected
vs 
actual

Nope

Can you post the call you're making that causes the error? I think you do need to cast it 
as Any
but your comment 
: Any
is making me wonder what's going on.
I would imagine you would have something like:
Copy code
val genericVal = getGeneric()
val data = getData()
<http://Request.Post|Request.Post><genericVal as Any, data>()
and not 
<http://Request.Post|Request.Post><genericVal : Any, data>()

I think 
Any
in your case is the type parameter, equivalent to 
T
or anything you want to call it. Can you post the method signature of `POST
a

you can use *

Any isn’t a generic , its a Type. so it would <T: Any>
Your probably thinking of Star Projection in kotlin
