I may be being a killjoy, but:

({
	[0] = function ()
		print(0)
	end,

	[1] = function ()
		print(1)
	end
}[value] or function ()
	print("default")
end)()

Admittedly, this will probably generate a fair bit of garbage, but it is O(1).

Is the compiler clever enough to optimise function closures that take no 
parameters and never leave the parent function?
