That is news to me.  Why is include_once a performance drag?  What is
the better programming logic, that doesn't just duplicate the
behavior?

I have always just used include_once because it is more similar to the
import statement from other languages.  My assumption is that calling
include_once hundreds of times on the same file, is not as bad as
accidentally importing twice, but I don't have any data to back that
up.
