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!
