Jigsaw @ JavaOne 2015

[Stephen Colebourne]

I've also been somewhat concerned that the two namespaces are similar,
but concluded that it is best that way. Using underscores, dashes or
anything else would be more confusing, given that the emphasis is on a
namespace concept within the JLS.

I do find remembering which is which, module vs package, in
module-info.java is a little confusing, but I suspect we'll get used
to it. I wouldn't object to using "requires module com.foo.bar"
however.

I'm more concerned about some other aspects of the module spec, which
I'm still pondering.
