Like with all relaxations of the rule 'a metamethod is called only when
the operation would be invalid', by calling the function 'rawconcat',
which would be added to the raw* API group (with rawequal, rawset,
rawget).

I'm not advocating that addition though, these relaxations beyond
complicating the language also slow it down, they should be kept to a
minimum.
