Is it possible to specify the type of a function reference in the very same expression I'm referencing in? for example, instead of

val function: ((Char) -> Unit) = ::println
println(function)

something like

println(::println) // but this fails because it's ambiguous

println(::println as (Char) -> Unit)

if I remember correctly.

I tried that (including the missing parentheses) but it didn't work. It seems the compiler tries to get the reference and then cast it
