There was a new option added in JDK 1.2 (I think) that says something along
the line of "everything in package X comes from this .jar file". It turns
out that this gives license for many of the same kinds of intra-library
optimizations. There is a good paper in OOPSLA'00 proceedings discussing
this feature and some of its implications. The authors mention Dylan's
sealing in their introduction, though from their discussion I think maybe
they didn't quite get all of its implications. Sorry I'm a bit fuzzy on the
details, but my copy of the OOPSLA'00 proceedings is at home right now.
I'll try to remember to look it up when I get home and post a proper citation
tomorrow -- I think the paper had a title that would make it obvious if one
were looking for something on this topic, in case somebody else has a copy of
the proceedings handy.
