comment Passing a variable messages list to Quiet
@episanty Yes, it works by preventing evaluation of the message list using Hold and then transforming the expression into a call to Quiet. Whether or not to use the auxiliary variable messageList, or to represent the empty message list using Hold[], are choices that can be made to suit one's taste (and the form of the "real" version of g).
