Comment (by albertov):

 Replying to [comment:13 hsyl20]:

 z-encoding], hence "zd" is "$" and "zu" is "_" . You can remove the `$w`
 prefix probably introduced by the worker/wrapper transformation, leaving
 you with `poly_go13` or maybe `poly_go` in the Haskell source.

 There's no function by those names in that module, however, I could manage
 to find "poly_go13" it's header (.hi) file. It's in a binary format which
 gives me no hints regarding where it might come from. Is there any way to
 inspect it in a more amicable way? Thanks!
