It is yet another use case for `scope` storage class. Locking 
`shared` variable via mutex should return same variable but 
casted to non-shared `scope` (somewhere inside the locking 
library function). Then it is safe to pass it to functions 
accepting scope parameters as reference won't possibly escape.
