Thanks for the reply. It would be great to get this added to the DOCS so
that the next person doesn't spend a day trying to figure it out too.
Also, which is faster: using '3' or 3::int8? I presume shorter is
quicker to parse, but is there an advantage over treating it as an
unknown and an explicit cast?
