    Remove const qualifier from object that can be modified · ac746100

    Modifying an object declared const is technically undefined behavior,
    and compilers are entitled to do as they like with such code. The most
    likely result - in the event of some future optimizer - would be
    elimination of the code performing the modification, although it could
    theoretically be anything.
    Given that ConstantPropertyMap defines an assignment operator already,
    simply changing the underlying data member to non-const (while making
    it private) seems to achieve the same result as the current code while
    avoiding UB.
