 | Agree completely.

That would bring to 6 the number of procedures (of 19) imported from
SRFI-60 (and SRFI-33).  Shall we continue piecemeal; or should the
incorporation of SRFI-60 procedures be considered in a more organized
fashion?

* bitwise-and
* bitwise-ior
* bitwise-xor
* bitwise-not
  bitwise-merge
  any-bits-set?
  bit-count
* integer-length
  first-set-bit
  bit-set?
  copy-bit
  bit-field
  copy-bit-field
* arithmetic-shift
  rotate-bit-field
  reverse-bit-field
  integer->list
  list->integer
  booleans->integer
