I've perused both the spec[1] and Andrei's book, and I the idea I
get is that module declarations are optional, recommended only in
case of file names not being valid D names. But in the community
(and Phobos) I see it's strongly recommended and used throughout.
What's the reason? If the declaration overrides the path
(provided the file is found) rather than enforcing path
consistency by outputting a compile error, then what's the
benefit of module declarations, if we have to be disciplined to
keep it consistent with paths anyway?
I'm busy starting my first big multi file D project, thanks for
any feedback!
