Proposal: Add cons function to Data.List module

[Helmut Schmidt]

Taylor,

Is it really necessary for you to be so rude? I can assure you that my
proposal has been made in the same good faith as your proposal which
inspired mine.

Besides that unnecessary snark you do make an excellent point regarding the
poor discoverability of the list constructor which I imagine must cause a
lot of confusion among newcomers.Thank you for keeping an open mind!
