Make "swap" a top-level function
In the module,Control.Arrow, in the definition for second, there is a utility function defined: swap, which takes a pair, and returns a pair with the first and second members in opposite places. I would like to see that function broken out of the Control.Arrow module, and made a top-level function in the Data.Tuple module.
