Macro enso_prelude::f

macro_rules! f {
    ([$($name:ident),*] ($($args:tt)*) $($expr:tt)*) => { ... };
    ([$($name:ident),*] $($expr:tt)*) => { ... };
    (($($args:tt)*) $name:ident . $($toks:tt)*) => { ... };
    (($($args:tt)*) { $name:ident . $($toks:tt)* }) => { ... };
    ($name:ident . $($toks:tt)*) => { ... };
}

Clones all arguments from the first argument list by using CloneRef and defines lambda with arguments from the second argument list (if present). For example, the following usage

f! { (a,b)(c) a + b + c }

is equivalent to:

{
    let a = a.clone_ref();
    let b = b.clone_ref();
    move |c| { a + b + c }
}
