all accumulators should be available as expressions

      Not clear why $first $last and $addToSet are the only accumulators not available as regular expressions with array argument.  In particular $last is helpful to avoid very verbose syntax for $arrayElemAt plus calculate position of last element ($subtract 1 from $size)
