PHP is a not a type strict language, far from it and it is unlikely it'll ever be such. It is also a not pure OOP language and I very much doubt it'll ever be one. While GOTO can be abused, so can any other language feature, such as OOP, or the ability to include remote files. If we add this feature certain warnings should made about it using it (as with almost any feature), but I see no reason to cripple advanced users simply other users may find fun and usual ways to abuse this useful functionality. Anyone who has ever written a parser will tell you GOTO is absolutely essential unless you want to go into recursive functions etc... which are way slower. GOTO also provides a fast an safe alternative to many solution where so far the only viable option (for most people) have been a recursive functions and those tend to smash the stack once in a while.
