When converting from COM to Lua, the default behavior is to
transform variant values to the closest Lua type. The script can
change the conversion from Lua types to a table describing the
variant, by setting the TableVariants field of the
luacom table(the LuaCOM namespace) to true. The
tables will have a Type field telling the original type of
the variant, and a Value field containing the conversion to
the closest Lua type. Be careful with this feature, as it may break
compatibility with other scripts.
