It just occurred to me that we have a lot of places in WebKit were we
ASSERT(foo) (where foo is some passed in Foo* pointer which should never be
Maybe it would be cleaner/better/whatever if we instead used a template to
do this ASSERTing in a centralized place.  The primary advantage would be
that the ASSERTion is clear in the method signature.

void doSomething(Foo* foo)


void doSomething(NeverNull<Foo> foo)

Could get nasty when interacting with other templates though.  I don't think
we want a NeverNullOwnPtr, or maybe we do?

Does this seem useful to anyone else?  Oh c++ experts, does this even seem
possible, seem like it would perform well, not bloat the code size, etc?
