The idea is not to allow both '-' and '_'. This way you can always use
internally the one which is appropriate ('-' for dns names, '_' for
identifiers). I've seen Java packages named with '_' where the domain used
'-', for example.

Given the above the idea is to use just one all over the place, for
consistency. I chose '-' because DNS plays an important role - more
important than programming language identifiers. Also MIME etc. uses '-' as
a separator rather than '_', and YAML is similar in spirit.

I don't think this is a problem... is it?
