Comment (by andrewthad):

 I don't know when this was fixed, but I just tried the attached
 reproducible case with GHC 8.2.2, and specialization occurs as expected.
 This came up because I was working on another project and realized that
 inlining did not block specialization like this comment:19 suggested it
 would. I think this ticket should be marked as resolved.
