whiteout
provides macros that erase the type of any value into an impl Trait
for a given trait. This gives you a value that can only be use with the methods of that trait, and whose type is unnameable.
```rust
fn main() {
let a = erase!(10, std:ops::Add
Since we sometimes want to use these values together,
whiteout` provides both a one-time macro and a macro that produces a function which returns a consistent unnameable type, allowing multiple erased values to be used in conjunction. See the documentation for more info.
