Yes.

I am adding this section to the Rationale:

  Homogeneous Numeric Arrays

  SRFI-63 introduces homogeneous arrays. This SRFI introduces
  denotations for homogeneous arrays following the rank and/or
  dimensions; and separated from them by a colon (:).

  The names of the array-prototype-procedures of SRFI-63 and aliases
  for the array-prototype-procedures of SRFI-47 match these type
  denotations with A prepended. Having the array-prototype-procedure
  names match the array type denotations reduces the memory load for
  users.

  All implementations must accept all the type denotations, but need
  not implement all the homogeneous array types. Those homogeneous
  types which an implementation doesn't support it stores in next best
  homogeneous array type, defaulting to heterogeneous arrays in the
  worst case. The rules for casting unsupported types are given in
  SRFI-63.
