I once had a function with an argument called system-name. Suddenly
Emacs started to complain that some files are locked by some other user.
How many people now that system-name is a global variable and used by
the file-locking code? The lesson is that Emacs should not pre-define
global variables with names that are likely candidates for local
variables.
