I'm little scared about such lock function, where order of lock
operations is disconnected from order of unlock operations. However this
is something that possibly could be fixed - I'm thinking about building
chains of locks.

Right, this is weak point of moving difference in lock semantics from
compile time to runtime. Now I agree with you that we should take
benefit of type system to avoid such problems.
