       Force the object into a specific type. Can be used to force certain
       upconversions (or avoid them).
 
    valuation(sub { ... })
    val(sub { ... })
       Takes a subref, creates a valuation that represents it. The subref will
       get the record as its first and only argument.
 
       Example(s):
          To get the square of the "x" field:
             val(sub{ $[0]->{x} ** 2 })
 
    xform(<aggregator>, <snippet>)
       Takes an aggregator and a snippet and produces an aggregator the
       represents invoking the snippet on the aggregator's result.
 
       Example(s):
          To take the difference between the first and second time fields of the record collection:
             xform(recs(), <<{{1/time}} - {{0/time}}>>)
