How does the real php-interpreter deal with it? The most logical approach 
would probably be multiple passes: One for building types, and one for doing 
the rest.

However if you want to cater this special case without having to do that, you 
could think about creating a forward-declaration of "class Foo" on "new Foo;" 
when Foo is not found.

Then you would have to deal with forward-declarations during search though.
