How about foo(m[5]) Same thing right? m[5] is being
assigned/copied/rererenced to the first argument of foo. Thart won't
be helped by defining a new operator.
Look, he wrote:

when I write m[5] and there's no m[5], I think there are only two
things that are okay to happen.

Either m[5] returns NULL (a passive indicator that there is no m[5],
like you'd expect from C) or m[5] throws an exception (an aggressive
indicator that there is no m[5], like you'd see in python).

What is so difficult to understand there?

There is a C point here. The original author (at least I think this is
a quote) is mistaken about C. If m[5] does not exist, it would be
wrong to expect NULL.

The C behavior should be an exception
(exception address violation).

In my implementation, overloading of the operator [] can throw an exception
if you define it like that.

I quoted the blog because it confirms my implementation of operator overloading
using the []= operator as a different operator than [] and =.
