More consistent use of Names.
Several large helpings of tedium later, fewer strings are being
discarded like so much refuse. Some names now cache a String, but only
"named Names", so it's not very many and they pay for themselves pretty
quickly. Many fewer name-related implicit conversions now taking place.
A number of efficiency related measures.
