`BLMOVE` is the blocking variant of `LMOVE`. When `source` contains elements,
this command behaves exactly like `LMOVE`. When used inside a `MULTI`/`EXEC`
block, this command behaves exactly like `LMOVE`. When `source` is empty, Redis
will block the connection until another client pushes to it or until `timeout`
is reached. A `timeout` of zero can be used to block indefinitely.
This command comes in place of the now deprecated `BRPOPLPUSH`. Doing
`BLMOVE RIGHT LEFT` is equivalent.
See `LMOVE` for more information.
@return
@bulk-string-reply: the element being popped from `source` and pushed to
`destination`. If `timeout` is reached, a @nil-reply is returned.
## Pattern: Reliable queue
