files presented to the compiler. Typically this means that it repeats
the files listed in GoFiles and then also adds the Go code generated
by processing CgoFiles and SwigFiles. The Imports list contains the
union of all imports from both GoFiles and CompiledGoFiles.

The -deps flag causes list to iterate over not just the named packages
