Strictly speaking, positive numbers are reserved for slot types declared
via SLOT_TYPE_N, and also it was a sort of expansion on the current
(internal) convention that the slot type of d-slots is -1.

But, other schemes might be devised.  100+n, or (max_n)+n, etc.
Decoding these might be slightly harder, and/or involve assumptions
about the maximum number of slot types that would ever be declared.
