One class per object file isn't a problem - you can always .jar your
classes if the proliferation of small files bothers you, and then it's
just a different way of indexing the mound of code.

One class per source file complicates the human's view in order to
simplify the tools'. Not sure that's really worthwhile.

Yeah... of course you can easily simulate globals with static members
in a dedicated class, but it's slower. THIS, though, is where Java's
security model comes in - you can assign security X to Globals1.class
and security Y to Globals2.class, rather than trying to juggle
security issues in a monolithic "globals" namespace. IMHO it's not
worth the hassle, though. I'd rather just have globals.
