52 namespace or class. The simple form of statement "use A\B\C\D;" is
53 equivalent to "use A\B\C\D as D;". The use statement can be used at any
64 namespace A\B\C;
69 A special constant __NAMESPACE__ contains the name of the current namespace. 
73 namespace A\B\C;
86 current import rules. So if we have "use A\B\C" and then "C\D\e()"
87 it is translated to "A\B\C\D\e()".
89 current import rules. So if we have "use A\B\C" and then "new C()" it
90 is translated to "new A\B\C()".
96 inside namespace (A\B) first tries to find and call function from current 
97 namespace A\B\foo() and if it doesn't exist PHP tries to call internal
103 of failure uses internal PHP class. Note that using "new A" in namespace 
105 using "new \A" you are able to create any class from the global namespace.
107 A\B\foo() first tries to call function foo() from namespace A\B, then
108 it tries to find class A\B (__autoload() it if necessary) and call its
111 namespace. So "new A\B\C()" refers to class C from namespace A\B.
