just throwing it out how about list comprehensions in kotlin kotlinlang #language-evolution

a few years back, JB released annual public poles about how receptive to a handful of potential features the community were. it included list comprehensions, but they proved to be middlingly popular, and afaik, JB has yet (if ever) to announce any intentions to include them in Kotlin otherwise.

Yeah i thought a library would be a good start to test the waters

I am still learning and deciding whether to go native route or not

list comprehensions are a bit like regex in the way of very: "easy to write; hard to read"

And haven't been able to get my hello world library working

Yeah in ruby had to do a lot of interesting metaprogramming

To get it work I'm sure it's gonna be an adventure

Thanks

Yeah I am more interested in it as intellectual exercise and as an ambassador to language like Julia python to try kotlin

I wouldn't imagine using it much personal ly

Can be fun and good for multiple dimensions and prototyping

And good for beginners don't have to learn filter map or filtermap etc.

i bet, but i'll give it a shot if you do. i like the idea for sure. would feel weird without list literals, though:

listOf(x * 2 for x in 3..6)

just doesn't feel right by comparison to

[x * 2 for x in 3..6]

you might want to play with a syntax for the default

it

iterator value, too

listOf(it * 2 in 3..6)

or something

Sure it could be open source
