	== Notes ==		== Notes ==
	The difference between ''wipe(table)'' and ''table={}'' is that ''wipe'' removes the contents of the table, but retains the variable's internal pointer.		* While this function returns an empty table, it is not necessary to assign it to a variable.

			local t = {"stuff"}
			t = wipe(t)
			print(#t) -- prints 0

			local t = {"stuff"}
			wipe(t)
			print(#t) -- also prints 0

			* The difference between ''wipe(table)'' and ''table={}'' is that ''wipe'' removes the contents of the table, but retains the variable's internal pointer.
