when calling a trait method expecting one unit type argument, hint for E0061 puts the unit type in the wrong position

[tinaun]

#![feature(fn_traits)]

fn main() {
    let closure = || { 3 };
    
    closure.call_once();
}

becomes:

   Compiling playground v0.0.1 (file:///playground)
error[E0061]: this function takes 1 parameter but 0 parameters were supplied
  --> src/main.rs:18:13
   |
18 |     closure.call_once();
   |             ^^^^^^^^^
   |
help: expected the unit value `()`. You can create one with a pair of parenthesis
   |
18 |     closure.call_onc()e();
   |
