OK, good we're on the same thought track.

Agreed.

How would a user feel if the localizing check broke down multiple
delcarations into single declarations as a by-product?

In other words:

int i, j, k;
// many lines of code
i = 10;

becomes

int j;
int k;
// many lines of code
int i = 10;

Would this be unacceptable?
