One problem with this function is demonstrated by

    string s = "hello world";

    ConstAssign(h[0],'j');

Oops - it assigns invariants too! Even if you can be sure there are no
other threads vying for access to s, still, those chars might be in a
hardware-locked ROM segment.

There's a reason why casting away const is not defined.
