Some time ago I noticed that I usually only need to change variable only couple of times, maybe 3 :)
So I considered that we’re only interested in restricting programmers ability to write more than n times.

Just to throw it out there as a possible syntax:
const[n] int x = 0;

Writing enabled up to n times, its type could simply be const[n] int with possible equality to const int.

Cheers, Filip
