How does an unqualified function name or unqualified constant name like name resolve?

Function or constant names that do not contain a backslash like name can be resolved in 2 different ways. First, the current namespace name is prepended to name. Finally, if the constant or function name does not exist in the current namespace, a global constant or function name is used if it exists.
