Name for unary unboxed one-tuple

Dear Libraries Committee Some time ago Andrew Martin asked youhttps://mail.haskell.org/pipermail/libraries/2018-January/028419.html what the name of the unary unboxed one-tuple type and data constructor should be. The thread ran for a while, but you never came to a conclusion. Can we nail this one? You’ll see on Trac #14673https://ghc.haskell.org/trac/ghc/ticket/14673#comment:19 that chessai wants me to decide 😊. But it should really be you. To me, there seems to be something of a consensus around Solo#. Simon PS: actually I think Andrew may have addressed libraries@ rather than core-libraries-committee@ by mistake.
