You accidentally left the first const in there. This is a case where I
like multiple declarators in one declaration because of the close
relationship between them:
for (int i = 0; i < N; i++) {
const int i_ = i, i = i_;
...
}
I note that if C had "syntax" macros like Lisp, you could define such
constructs in the language itself.
