The larger the program, the greater the likelihood of inadvertent name
collisions creating rare and irreproducible interactions between
different and supposedly independent parts of the program that each
work fine on their own, and supposedly cannot possibly interact.

That is handy, but the larger the program, the bigger the problem with
names that are over used, rather than unused.
