The the slots, usually it's just that code that uses EIEIO seems to
misuse a weird feature of EIEIO, so they use the initval keyword instead
of the slot name when accessing the slot. For example, often code will
do
(slot-value x :file)
where the slot's name is not `:file` but `file`, so the correct usage is
(slot-value x 'file)
This odd usage does work for historical reasons but is deprecated, hence
the warning.
