I'm trying to write an RAII wrapper on Linux.
I understand struct in D doesn't have default constructor (for

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.

Thanks for your help. NRVO looks interesting. However this may
not be RAII after all. Or may be too much of C++ has spoiled me.
I am not familiar enough with D to appreciate/question the
language design choice. I'll accept this and move forward and see
how my code evolves. Nevertheless, I'm still learning something
new. :)
