can i do the following
mapOfGum is a map of different pieces of Gum, key=String flavorName
i would like gum to reference the peppermint piece in mapOfGum
i can easily get a copy of the peppermint piece and assign it to gum, but i only want 1 gum that is peppermint, the 1 that resides in the map. because gum takes up space.
