Converts a curried function to a function on a triple.

Uncurries a function expecting three r, g, b parameters.

Convert a curried function on Sigma to an uncurried one. Together, currySigma and uncurrySigma witness an isomorphism. (Refer to the documentation for currySigma for more details.)

uncurry with no lazy pattern matching for more efficient code.
