Comment (by andrewthad):

 You're right. To actually make this be safe, we would have to redefine
 `StableName#` as well:

 {{{#!hs
 data StableName# s a
 makeStableName# :: a -> State# s -> (#State# s, StableName# s a#)
 }}}

 And now you can't use `runST` create a `StableName` at the top level like
 you did before. But, now this becomes a more annoying change to make.

 I'm going to go ahead and close this because, as you've pointed out, it's
 not as simple to do as I thought, and because I've realized that I don't
 actually need to use `StableName` to accomplish the thing I was originally
 planning on doing.
