-* An empty table is always converted into a MessagePack map, the rationale is that empty lists are much more common than empty maps (usually used to represent objects with fields).

 * A Lua number is converted into an integer type if floor(number) == number, otherwise it is converted into the MessagePack float or double value.
 * When a Lua number is converted to float or double, the former is preferred if there is no loss of precision compared to the double representation.
 * When a MessagePack big integer (64 bit) is converted to a Lua number it is possible that the resulting number will not represent the original number but just an approximation. This is unavoidable because the Lua numerical type is usually a double precision floating point type.
