Comment (by simonpj):

 > `[lq| inline gt |]` attaches an annotation to gt, so perhaps the
 solution should be to tell the desugarer not to consider any function with
 an annotation attached as dead code.

 I'd be happy with that.  But can you remind us HOW `lq` "attaches an
 annotation"? It it documented in the user manual?
