Move clearValue inside Value mkInt instead of setInt mkBool instead of setBool mkString instead of setString mkPath instead of setPath mkNull instead of setNull mkAttrs instead of setAttrs mkList instead of setList* mkThunk instead of setThunk mkApp instead of setApp mkLambda instead of setLambda mkBlackhole instead of setBlackhole mkPrimOp instead of setPrimOp mkPrimOpApp instead of setPrimOpApp mkExternal instead of setExternal mkFloat instead of setFloat Add note that the static mk* function should be removed eventually
