What purpose to const besides functional programming?

Yes, but you still seem not to understand what an invariant function is,
and why it should exist. An invariant object (read: invariant data)
/can/ be accessed without syncing. An invariant method cannot. Invariant
functions are not and should not be pure functions. The two are
different kinds of beasts. One is functional programming, the other is
not.
