<msimberg>
^ i'm trying out making a pull request, let me know if i've missed something in the process
<heller>
msimberg: looks good so far. please don't edit the pr and issue list for typos, those should be verbatim copies of what we have tracked with github
<msimberg>
ah, sorry, that makes sense
<msimberg>
i'll remove that one

ok, for some reason or another, when concurrently scheduling and removing a PU, the thread gets silently dopped :/

No new failures overnight, just varying degrees of the same old ones.
<hkaiser>
heller: fixed now?
<heller>
Yes
<hkaiser>
nice!
<hkaiser>
thanks - will look

K-ballo: yt?
<K-ballo>
yes
<hkaiser>
K-ballo: hey
<hkaiser>
what do I need to do to make unwrapping support optional and variant?
<K-ballo>
oh yikes
<K-ballo>
let me see, I'm not sure what it will take after the GSoC changes
<hkaiser>
is it built around some traits system I could add stuff to?
<K-ballo>
no idea
<hkaiser>
ahh, I thought you looked at it for the changes you made
<hkaiser>
I can ask the student as well
<K-ballo>
no, I didn't get to yet, I'm waiting for the final PR to be merged
<K-ballo>
I expect it to be harder after GSoC, not easier
<hkaiser>
K-ballo: I don't mean the async stuff
<hkaiser>
K-ballo: btw, I'm fine with merging the async PR, I was just cautious as heller and you were working on fixes for the non-async unpack
EverYoun_ has joined #ste||ar
<K-ballo>
if I attempt to fix the current issues now I'll completely conflict that PR
<hkaiser>
we'll do it however you prefer
<K-ballo>
it looks like I will end up once again inheriting unwrapping, much to my dislike, so I'd rather fix it once after the PR is merged than once before and then again after
EverYoung has quit [Ping timeout: 255 seconds]
<heller>
hkaiser: i was not working on it. The cuda stuff required a different fix
<hkaiser>
should we merge #2829 first?
<hkaiser>
K-ballo: ok, I'll go ahead and merge it, then
<K-ballo>
I think there were some open items still
<K-ballo>
mmh, apparently just a feature test for override
<hkaiser>
for variants it would be sufficient to support variant<T, future<T>>, everything else would be impossible anyways, I think
<heller>
optional<future> sounds odd
zbyerly_ has quit [Quit: Leaving]
<hkaiser>
heller: you are right, optional might not be needed after all
zbyerly_ has joined #ste||ar
<heller>
variant should be doable for any number as well
<hkaiser>
heller: well, we'd have to be careful not to create a variat<T, T>
<heller>
right...
<K-ballo>
a `variant<T, T>` is fine for std::
<hkaiser>
restricting it to variant<T, future<T>> might be easiest as this wouldn't require any type transformations
<hkaiser>
K-ballo: what does it do?
<K-ballo>
it holds one of two `T`s
<hkaiser>
and index() is always == 0?
<K-ballo>
no, the discriminator is salient
<K-ballo>
it holds either the first `T` or the second `T`
zbyerly_ has quit [Quit: Leaving]
<hkaiser>
lol
<hkaiser>
how do you setthe second T?
<K-ballo>
setting either T has to be done via index
<hkaiser>
ahh, ok
<hkaiser>
but get_if<T> would return the first one, I guess
<K-ballo>
no
<hkaiser>
whichever is set, yah
<K-ballo>
get_if<T> doesn't even compile, can't tell which index you mean
<hkaiser>
ohh
<K-ballo>
whenever a discriminated union has duplicated types access must be by index
<hkaiser>
K-ballo: anyways - you tell me when to merge #2829, ok?
<K-ballo>
heller: you reviewed #2829, do you approve it?
<heller>
K-ballo: id have to look again, I'm fine if your fine
<K-ballo>
I have not reviewed it myself

heller: do we need to explicitly merge master into #2829 to get a current CI build, or does circle test PRs as if merged?
<heller>
