A function (such as my 'before function)
that uses:
either found: find data key[pick data (index? found) - 1][none]
Is easy enough to write and is probably acceptably efficient,
but to implement it in the "C" code so that 'select would
have a 'before refinement would be most useful...
and speed up performance.
