# `lazycall`

is very useless. It allows for automatically moving the computation of arguments
into a called function.

```rust
#[lazy]
fn myfunc(a: i32) -> i32 {
  a + 1
}

fn main() {
  println!("{}", lazycall!(myfunc(some_expensive_func())));

  // essentially:
  println!("{}", myfunc_lazy(|| some_expensive_func()));
  // wherein myfunc_lazy() evaluates the specified closure.
}
```

It is mostly to be viewed as a finger exercise in procedural macros.
