But in practice, it does prevent accidental mutation, and as
long as the programmer is behaving themselves reasonably well,
Unfortunately, the net result is that while const is still very
useful, there are a lot of cases in D where you can't use it,
and you have to be a lot more careful about how and when you
use it such that it gets used far less than in C++, and while
where it _is_ used does provide much better guarantees, you
lose out on a lot of protection against accidental mutation
that your typical C++ code gets.
Things would be a bit friendlier for newcomers if the
documentation were a bit clearer on the 'having to be a lot more
careful on how and when you use it' so one doesnt end up finding
this out the hard way.
