00:34 <dh`> those seem to be mostly workarounds for missing language features in java

00:34 <dh`> (there's a truism to that effect about design patterns)

00:40 <companion_cube> @smondet yeah, then use Caml for 10 years and realize that OOP is genuinely useful for the 5% where objects are good :D

01:20 <discocaml> <deepspacejohn> it recently occurred to me, is oop used for anything at all in the stdlib?

01:23 <companion_cube> I don't think so?

01:25 <discocaml> <yawaramin> well, there's the `Oo` module

01:25 <companion_cube> I've never used that one :DD

01:27 <companion_cube> but really that's a support module, nothing in the stdlib _relies_ on OO

01:28 <companion_cube> maybe for bootstrapping reasons, I'm not entirely sure

03:31 <matsurago> hi, just wanted to try OCaml on Windows, but I had to interrupt 'opam init' at some point. After restart, the init command doesn't understand it was interrupted and proceeds to next step (which ofc fails). Any advice how to restart opam init from scratch?

04:54 <Guest41> Hi, I have learned about variant types and they seem useful for picking "one out of" a bunch of values. e.g. `type weekday = Monday | Tuesday | ...`. Is there a built-in feature that allows me to create variables that pick _multiple_ out of a bunch of values (without making some sort of Set of weekdays, etc.).?

04:56 <dh`> there is not, afaik

04:57 <dh`> you could make a sum of all the legal combinations but that is nasty to write down and nasty to work with

04:57 <dh`> there might be some kind of ppx thing to generate that for you but probably you just want a Set

04:58 <dh`> matsurago: easiest is to just delete whatever the windows equivalent of ~/.opam is and start over

04:59 <Guest41> Good to know, thanks!

05:48 <matsurago> dh`: thanks, I think I found an 'opam' folder inside AppData/Local, hope this is it

17:38 <discocaml> <thearthurm> Well it also depends on how you define oop

17:38 <discocaml> <thearthurm> Smalltalk oop is different then simula oop is different than lisp oop

17:41 <discocaml> <mohamed_abdulsalam> have you tried wrapping the command in `dk.Ml use -- env ...`?

17:57 <discocaml> <yawaramin> maybe polymorphic variants? see eg https://aantron.github.io/dream/#status_codes

18:01 <discocaml> <yawaramin> would allow you to do eg `let working = function #weekday -> true | #weekend -> false`

18:01 <discocaml> <yawaramin> assuming you have `` type weekday = [`Mon | `Tue | `Wed | `Thu | `Fri] `` and `` type weekend = [`Sat | `Sun] ``
