() represents the empty (length-0) tuple. 9.8 Named Tuples The components of tuples can optionally be named, in which case a named tuple is constructed: julia> x = (a=2 code loading mechanism allows the same package name to refer to different packages in different components of an application. Julia supports federated package management, which means that multiple independent to your project. The mechanism for combining the roots, graph and paths data structures of the components of an environ- ment stack is simple: they are merged as dictionaries, favoring earlier entries
