No.

It was never correct.

Immutable is a very strong guarantee that the memory will never change.

The compiler in such a case is free to put it into read only memory and 
as a result crash if you tried to write to it.

You can use const instead which doesn't have any such guarantees and 
it'll work with a pure function :)
