I'm very far from an expert as well, but as I see you could have automatic currying in the same way I can write in Julia x -> f(x, 10) (manual currying using anonymous function) but automatically for every function. But the language would have to disallow using them for dispatch purposes:

f :: (Int -> Double) -> Int -> Double

That would have to dispatch to

f(::Function(::Int, ::Double), ::Int)::Double

Now the dispatch will have to be recursive (it will have to apply to each argument and arguments arguments to evaluate which is more specialized), making finding the most specialized version of a function even more chaotic. I'm trying not to think what dispatching on return types means for the compiler though (and that's not necessary for the auto currying).

And because of the currying, if you apply the first argument you'd have a (g :: Int -> Double) which has the memory of receiving (Int -> Double). But now trying to dispatch on another function with that partial will it dispatch as if it were a normal Int -> Double or will the "knowledge" of receiving a previous argument change which method it will pick?

To be honest I have no idea, it's probably possible but it feels like it would be something very different from Julia.
