@turansky just seen a new 
JsPrimitive
annotation on wrappers, from Seskar. What does it do?

It's for 
Symbol
and 
BigInt
. It will correct 
is/as
operator calls
Copy code
// Kotlin
a is Symbol

// JS - default
a instanceof Symbol

// JS - with plugin
typeof a === 'symbol'

Sounds good! Thanks
Functional question: I see you wrapped
Copy code
jsTypeOf(o) == type
in your own function 
seskar.js.internal.hasType
. Is this because it's easier to implement the compiler transformation? (instead of building the 
jsTypeOf(o) == type
expression)

Yes
gratitude thank you 1
In any case 
hasType
will be inlined
