Suggestion: Shorter keyword than target

[Boscop]

target is quite long to type, and it becomes noticeable when using the delegate macro a lot.
Could we shorten it for the next version of this crate? :)
E.g. how about using to as keyword, it also reads nicely, like "delegate to self.foo":

impl<S: Selectable> Switcher2<S> {
    delegate! {
        to self.switcher {
            pub fn page(&self) -> S;

            pub fn set_col(&mut self, col: Col);

            pub fn set_selected_brightness(&mut self, b: f32);
        }
    }
}

If you don't like to, how about for? It reads less like an English sentence compared to to, but has the benefit of getting syntax-highlighted in editors, and looks nice/familiar because it opens a block:

impl<S: Selectable> Switcher2<S> {
    delegate! {
        for self.switcher {
            pub fn page(&self) -> S;

            pub fn set_col(&mut self, col: Col);

            pub fn set_selected_brightness(&mut self, b: f32);
        }
    }
}

(Another possibility would be as but that already has a semantic connotation that could confuse readers in this context.)

to sounds really nice! Delegate to self.field seems like a very elegant sentence to read, good idea!.

for and as seem a bit weird to me in this place. Another one that comes to mind is with, but to seems better to me.
