That's actually not true. I ran a program on my system a long time ago that
ran ldd against everything in /bin, /lib, and all the various variants.

http://arsdnet.net/lib-data-sorted.txt

Notice that the *vast* majority of those libraries are used by only a
handful of binaries on the system. Half has five or fewer users.

This is slightly biased by not counting dynamically loaded things; ldd
only does statically requested shared libs. But I doubt that changes things
significantly.


Also note how at the bottom of the list, users go up quickly - the basic
system libraries are used by a great many apps. Most everything else is
pretty specialized though.

I don't remember where I put the source to the program that generated that
list, but it isn't too hard to recreate; it just counts references that
ldd outputs.

I'm sure the linker  will eventually take care of templates.

As to typeinfo, does D need it anymore? It seems like templates obsolete
most the typeinfo now.
