    but as you say - more allocation, extra complication
  • d
    it's silly really, but I have not had to write 
    while
    for a ... erm... while 🙂

    Could do 
    generateSequence { Unit }.map { if(shouldBeNull()) { null } else { calculateRandom() } }
    but there’s no perfect solution really.
  • d
    Yeah I think that would work
  • d
    I think a generateSequence function that expects an Optional written using the inline classes might be nice
  • d
    generateSequence { shouldBeNull() }.map { if(it) null else calculateRandom() }

  • c
    It’s not too bad.

    Oh that is neat! I've not seen that before 🙂

    Bit of a strange design choice. Trying to think of uses of it, and the only thing I can think of is a configuration map, but in that case what is wrong with getOrDefault? I certainly wouldn’t want to publish the map to another class with an explicit default, as that ties the implementations together.

    Check this, Chantry's favourite topic: https://www.meetup.com/kotlin-london/events/270844240/

    will tweet it out shortly - unless Steve/Milly want to beat me to it!
  • d
    looks good, and it's going to rain tomorrow, winner winner!
  • a
    Hahaha, loved the tweet!
  • c
    Found this discussion useful. Particularly the discussion around fun 
    CoroutineScope.x()
    and 
    suspend fun x() { … }

    Hi fwends. There doesn’t seem to be anyone running a Kotlin user group in Leeds at the moment so am considering starting one. Thought it’d be better to resurrect this than start a new one. Anyone want in on it? Have a venue and a couple of potential sponsors lined up.

    Where the Kotliners at? Ben Dale at SGI is organising a Kotlin meet up in Manchester in May and is on the lookout for speakers. Is anyone here interested?

    not sure what to talk about? ChatGPT’s got your back

    I could potentially get involved.
