And this is the problem, that the description doesn't clearly match
the specification.

One might easily expect that library("pkg") implies use library "pkg"
for further package loading.

It's almost too bad that libraries weren't books, with packages being chapters, 
or libraries being postOffices, with packages being packages,
or packages being libraries, with libraries being cities
or libraries being libraries, with packages being books.

But the current mess wastes a good bit of time aggravating people who
want things just so, responding to people who are just careless.
