Its @safe except you can call non-safe functions. Same goes for nogc and 
pure.

Basically it verifies that you didn't do something stupid without 
limiting what you can call (like callbacks).

This is something I've been wanting for a while now due to potential 
mistakes with creating contexts with callbacks.
