-  Context (base : list Z).
-  (** [BaseSystem] implements an constrained positional number system.
-      A wide variety of bases are supported: the base coefficients are not
-      required to be powers of 2, and it is NOT necessarily the case that
-      $b_{i+j} = b_i b_j$. Implementations of addition and multiplication are
-      provided, with focus on near-optimal multiplication performance on
-      non-trivial but small operands: maybe 10 32-bit integers or so. This
-      module does not handle carries automatically: if no restrictions are put
-      on the use of a [BaseSystem], each digit is unbounded. This has nothing
-      to do with modular arithmetic either.
