Sure, but you can't do this, right?  You don't know where the
variable is defined until /after/ the file it's defined in is
loaded.  Sure, you can guess that links in a docstring for a
variable that is autoloaded from package foo may also lead to
other variables in package foo, but that's not foolproof.

I guess the help system could load the file of autoloaded
variables when showing their docstring, but people are bound to
complain about that too.
