<heller__> puuh

<jbjnr_> sorry. wasn't trying to urge you to look at it, just alerting that it's on my list
<heller__> sure

<maxwellr96> Is it possible on Rostam to download additional python modules?
<maxwellr96> and/or packages
<zao> The typical way you do it on clusters is to run `virtualenv` to create a Python virtualenv (possibly with `--system-site-packages`), `source venv/bin/activate; pip install blargh`.
<zao> Keeps most of the junk out of the system directories and your home directory.
<zao> (no idea how Rostam is set up, of course)
<maxwellr96> Okay, thanks! That's helpful

<K-ballo> what if we were to ditch one-shot bind and do proper category forwarding in util::bind ?

<hkaiser> K-ballo: how would know that we use it only once?
<hkaiser> we*
<K-ballo> convention, calling () on an rvalue
<K-ballo> std::move(f)();
<K-ballo> // do not touch f again
<hkaiser> ok, is operator()() && c++11?
<hkaiser> or was it 14?
<K-ballo> 11, but it felt as 14 since it was one of the last things to be implemented
<hkaiser> ok, then it should be possible, indeed
<K-ballo> and we already have bind_front/back that do value category correctly
<hkaiser> ok
<heller__> sounds pretty good to me
<hkaiser> otoh, in async(f, ...), 'f' is a one-shot even if it's not an rvalue
<hkaiser> but we don't one-shot it today anyways, so this is not an issue, I guess
<heller__> well, the category of f needs to be forwarded properly into the bind and probably also function
<heller__> but then, we move f into the closure of the task, this closure could (and I think it already is) and should be a one shot
<heller__> deferred_call uses a one shot bind, IIRC
<hkaiser> right
<K-ballo> async(f, ...) would be decay-copying `f` into some unique one-shot context already
<K-ballo> one of unique_function/one-shot-bind/deferred_call/...

<K-ballo> ref-qualified bind would not play well with unique_function, since that does an lvalue call
