* [bug#50618] [PATCH] import: stackage: Don’t try to update packages not available on Stackage.

Previously, the ‘hackage-package?’ predicate was used which meant that
the updater would try to update non-Stackage packages, and lead to messages
like these:

  $ guix refresh -t stackage
  warning: failed to parse https://hackage.haskell.org/package/hurl/hurl.cabal
  warning: failed to parse https://hackage.haskell.org/package/idris/idris.cabal

Since ‘hurl’ and ‘idris’ aren’t available on the current Stackage LTS release,
they should be filtered out before the Stackage updater even tries to update
them.

* stackage.scm (stackage-package?): New procedure.
(%stackage-updater): Use it.

since stackage-lts-info-fetch is memoized, wouldn’t it be cheaper
to look up the package there? (At least for lots of packages.)

Cheers,

Ah, good idea!  I will test if what the difference is terms of time.

Hmm, it seems to fail for me as well, but with a different error.  I
have attached the patch below.

Sure, but I think its easier for you to just apply the attached patch.
