Comment:

 The fact that `:info` doesn't work for `(~)` is being tracked separately
 at #10059.

 I'm not surprised that `:info (~R#)` and `:info (~#P)` don't work, since I
 wouldn't expect users to be able to make use of these (see also #15209,
 which proposes to remove the ability to query `:info (~#)`.) It's a bit
 unfortunate that `:browse GHC.Prim` exposes `(~#)` and friends—perhaps we
 could alter `:browse` to avoid printing them.
