A hack to control control-flow outside closures.

This crate allows one to do things like breaking loops outside a closure. It works through a a macro hack. Unless you really really need this, don't use it.

Example

#[macro_use]
extern crate control_flow;

loop {
    let closure = || {
        defer!(break)
    };

    // Breaks the loop.
    run_loop!(closure());
}
