 39.5.2 SRFI-4 Procedures
 ------------------------
 
 The procedures listed in this section are provided for all homogeneous
 numeric vector datatypes.  For brevity, they are not all documented,
 but a summary of the procedures is given.  In the following
 descriptions, you can replace `TAG' by any of the datatype indicators
 `u8', `s8', `u16', `s16', `u32', `s32', `u64', `s64', `f32' and `f64'.
 
    For example, you can use the procedures `u8vector?',
 `make-s8vector', `u16vector', `u32vector-length', `s64vector-ref',
 `f32vector-set!' or `f64vector->list'.
 
  -- Scheme Procedure: TAGvector? obj
      Return `#t' if OBJ is a homogeneous numeric vector of type `TAG'.
 
  -- Scheme Procedure: make-TAGvector n [value]
      Create a newly allocated homogeneous numeric vector of type `TAG',
      which can hold N elements.  If VALUE is given, the vector is
      initialized with the value, otherwise, the contents of the
      returned vector is not specified.
 
  -- Scheme Procedure: TAGvector value1 ...
      Create a newly allocated homogeneous numeric vector of type `TAG'.
      The returned vector is as long as the number of arguments given,
      and is initialized with the argument values.
 
  -- Scheme Procedure: TAGvector-length TAGvec
      Return the number of elements in TAGVEC.
 
  -- Scheme Procedure: TAGvector-ref TAGvec i
      Return the element at index I in TAGVEC.
 
  -- Scheme Procedure: TAGvector-ref TAGvec i value
      Set the element at index I in TAGVEC to VALUE.  The return value
      is not specified.
 
  -- Scheme Procedure: TAGvector->list TAGvec
      Return a newly allocated list holding all elements of TAGVEC.
 
  -- Scheme Procedure: list->TAGvector lst
      Return a newly allocated homogeneous numeric vector of type `TAG',
      initialized with the elements of the list LST.
