Do we need any (new) syntax at all?  What if we just make RValues
always do that where reasonable?  Then we can spell it add_const if
actually needed...

In fact, can someone come up with a good use case for needing more
than just character and string literals?  I feel like anything more
than that might be better left to spirit/regex/whatever.
