I, for one, don't have a problem with this. It certainly won't look
strange; people are used to that kind of syntax.

Another option might be {[ ]}. It's not FANTASTIC, but it's still (1)
obviously a table constructor (though a specialized type) and (2) a
syntax error in current Lua so it won't break any existing code.
