While it's not the prettiest of side effects in php, I don't agree it =
should be "fixed"

On top of a massive BC break, it's not as if the results are =
inconsistent. Learning php means learning how type juggling works.=20

At most, I'd remove the part that truncates numeric strings like =
"123abc" and always convert them to 0, because that's almost *never* an =
intended effect. One could argue that "123" =3D=3D 123 is, however.
