  Adding the `seq` method to all collections. Removing `pforeach`.

  Implementing foreach to work in parallel in ParIterableLike.

  Doing a bunch of refactoring around in the collection framework to
  ensure a parallel foreach is never called with a side-effecting
  method. This still leaves other parts of the standard library and the
  compiler unguarded.

  No review.

  Better signature avoidance. Review by extempore.
........
  r24547 | extempore | 2011-03-23 08:59:18 +0100 (Wed, 23 Mar 2011) | 11 lines

  My early attempts to implement non-integral ranges in a way which was
  useful without having lots of floating point traps were less than
  successful. One of the bigger backfires is that the requirement not
  to round (trying, and failing anyway, to avoid surprises with methods
  like "contains") inflicts runtime errors.

  The simple way to improve this, which seems a good idea anyway, is to
make the default math context something less inclined to exceptions.
Default BigDecimal mc is now DECIMAL128. References #1812, #4201 and
puts #4201 back to normal priority. Review by community. ........ r24548
