Is every single word really a reserved word in the global namespace?

Actually, it will not throw an error because classes are auto loaded.

The auto loader will not run because Directory is already registered.
It will instantiate a built-in Directory object.=20

An error would only be thrown if the file with the other Directory
class is manually included, which most people do not do anymore for
class definitions.
