I'm trying to write an RAII wrapper on Linux.
I understand struct in D doesn't have default constructor (for .init 
reasons).
I don't want to use `scope`.

Is there an elegant way to achieve this in D?
why not static method or free function that returns struct? due to 
NRVO[0] it won't even be copied.

 auto lock = MyWrapper();

`MyWrapper()` may return voldemort type, so user won't create your 
struct accidentally.
