What's the advantage of this compared to importing the "_.d" file
explicitly, i.e. "import pkg._;" ?
It is a paradigm shift to import a package.
Consider import std with a small sensible collection
of defaults from std.stdio, std.range and std.algorithm.
Or import gtkd and giving the library writer a defined place
for startup hooks. Also this scales much better to import
packages from non-directories, e.g. zip files or urls.
The other keypoint is that you have a simple way to obtain a packages
symbol.
This symbol can be handled as any other symbol,
e.g. apply protection, pass it as template parameter or alias different
packages based on a version tag.
Most of this is already possible but requires you to import a submodule to
obtain the package symbol.
