Macro lambda_types::call

macro_rules! call {
    ({$($wrapped: tt)+}) => { ... };
    ($name: ty) => { ... };
    ($name: ty , $arg: ty) => { ... };
    ($name: ty , { $($arg: tt)+ } $($arg2: tt)*) => { ... };
    ($name: ty , $arg: ty , $($arg2: tt)+) => { ... };
}

Ergonomic wrapper macro for calling a function.

Calling syntax is modeled around the lambda calculus, where:

• fx is translated to f, x
• f(...) is translated to f, {...}

So, for example, ab(c(de)f)gh translates to a, b, { c, { d, e }, f }, g, h.

The whitespace isn’t mandatory, but is recommended for readibility (see: a,b{c,{d,e},f},g,h).

This macro is hygienic.
