Puh, I think this was a valid attempt at putting things closer to =20
numbers rather then assumptions. Mark's claim was that ereg is being =20
used more than preg and I think these stats do put some doubt on that =20=

claim, even though it should also be noted that there are several ereg =20=

using functions that are not prefixed with ereg.
