Answer is probably no, but just checking anyway.
Context: I'm building a DSL / playing with macros. I am trying to get rid of the "::apply"
impl FooBar {
fn apply(x: X, y: Y) -> ...
}
is there anyway to register apply
as the 'default function' so we can do FooBar(x, y)
instead of FooBar::apply(x, y)
?
On nightly, you can use the fn_traits
feature to directly implement the Fn(X,Y)
trait.

I recommend against it, but types and values have separate namespaces, so you could do
struct Foo {}
#[allow(non_snake_case)]
fn Foo() {}
fn_traits
kinda-sorta works for singleton types, but it's not really what was asked for I think.
