Lua's table type is so general and versatile that a bit of discipline
in its usage does not come amiss. For most of my tables, I follow
the following rules.

1. The table is a proper sequence (§3.4.7 of the Lua 5.3 manual).
2. The [0] entry, if present, is an index to an arbitrary selection of
keys, usually a string with pieces gmatching "%a%w*" but
sometimes just a list of values.
3. I seldom use 'pairs'.
