Hi, everyone.

When I refer the document of thread library, a word "RALL-style" appear in
the introduction of the class lock_guard: This provides simple RAII-style
locking of a Lockable object, to facilitate exception-safe locking and
unlocking. 

I didn't got the main point of this word "RALL-style", could anyone tell me
the meaning ? Thanks.

Best wishes.
