I suggest adding storage classes for c64 and c128; like the others,
these can be implemented using plain vectors, but systems that have
specialized arrays of rectnums (two consecutive flonums) can exploit them.

The known is finite, the unknown infinite; intellectually we stand
on an islet in the midst of an illimitable ocean of inexplicability.
Our business in every generation is to reclaim a little more land,
to add something to the extent and the solidity of our possessions.
