No.  I meant if an exception was ignored, the procedure keeps going
without satisfying assumption.  For example,

|  Dir.mkdir('/usr')
|  Dir.mkdir('/usr/ports')
|  Dir.mkdir('/usr/ports/databases')
|  Dir.mkdir('/usr/ports/databases/postgresql-devel')

If you failed to mkdir('/usr') for any reason, successive mkdirs might
be meaningless.   Maybe I have to check out Common Lisp error system.
