Not quite. Note the initial /. When you do `using M` or `import M` it is like `cat /M` – it is relative to the root of the module system, not the current level of module. When you do `using .M` it is like `cat M` or `cat ./M` – it is relative to the current module. Otherwise when you wrote `using Gadfly` in your package, it would go looking for Gadfly inside your current module, which is unlikely to be where it is – unless you happen to have your own submodule called Gadfly, which is, of course, possible. If that's what you wanted, then you would use a relative import: `using .Gadfly`.
