This again gets to my nit regarding runtime features in a dynamically
typed language. One of the reasons type checking in C, C++, Java is a
good thing is its done at compile time, not runtime. Type mistakes,
especially in large libraries can be pesky things, often hard to check
for (and often harmless). A PHP script should not automagically bail
out on a type mismatch. I think that if this called in a try {} loop
an exception should be thrown (will this be achieved by George's patch?)
