Hi, John

Just to add an idea to yours ..

Do you think it's a compatibility-break if we'd decide to send a E_NOTICE
or E_WARNING if we f.e. try to give a string to a method that just allows
integer for this argument?
No break at all, just a E_NOTICE or E_WARNING as the script can succeed
anyways.

Bye
Simon
