I agree. Bignums should be analogous to lists; representation based
sublimits on size are acceptable only if they are so large that they are
like running out of memory. True, arrays and floats have size limits for
individual objects, but why should bignums be analogous to arrays and not
to lists? Page 13 of Steele says "storage is automatically allocated as
