[ghc-steering-committee] Re: GHC proposal: specification of static

I'm in favour. I tend to agree that we don't want a deprecation cycle because this holds back actual bug fixes. The GHC maintainers could backport a deprecation warning to every next minor release to give users notice that they need to slightly refactor their code. Am Mi., 3.

Like Moritz, in favour, with a deprecation cycle if possible.

Cheers, Erik

Dear Committee,

Simon proposes to simplify the specification of StaticPointers:

https://github.com/ghc-proposals/ghc-proposals/pull/732

https://github.com/ghc-proposals/ghc-proposals/blob/wip/spj-static/proposals...

...

...

I'd like to nominate Jakob as the shepherd.

Please guide us to a conclusion as outlined in

https://github.com/ghc-proposals/ghc-proposals/blob/master/README.rst#commit... .

...

If possible, please aim to make a recommendation by 9th December

...

As mentioned on the ticket, I'm in favour, _with_ a deprecation cycle.

I'm in favour of this proposal. It's simple, and, I would argue, more expected than the more advanced semantics that we used to have. Static pointers aren't very much used any way, so a small regression in capabilities isn't going to be a problem.

I did ask for an extra discussion in the Alternatives section on the Github thread, for the sake of future documentation. But this doesn't need to hold my vote.

Hey all,

our own Simon Peyton Jones proposes to simplify static pointers:

Static pointers are a feature < https://ghc.gitlab.haskell.org/ghc/doc/users_guide/exts/static_pointers.html> that allows you to get pointers to expressions that are valid across different processes and machines.

Allowing these expressions to reference certain types of local bindings has been producing issues that are hard to fix. The proposal suggests that instead we could just not allow that - simplifying both the specification and the implementation without placing a large burden on users (e.g. bindings can just be moved to the top level instead).

See the proposal itself for details:

https://github.com/ghc-proposals/ghc-proposals/blob/wip/spj-static/proposals...

...

I recommend *acceptance*. The cost of trying to figure out how to support the current spec is not worth the fairly marginal gain over

the

...

proposed simplification.

It would be great if I could get your responses on this by December
