just throwing it out how about list comprehensions...

just throwing it out how about list comprehensions in kotlin, i made a gem for Ruby support thinking of a Kotlin library for the same

[Hullaballoonatic]

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.

[Samuel Michael]

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

[Hullaballoonatic]

would it be a compiler plugin?

[Samuel Michael]

Ruby core team were not too thrilled either

[Samuel Michael]

Lol

[Hullaballoonatic]

i'd imagine not 😮

[Samuel Michael]

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

[Hullaballoonatic]

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

[Samuel Michael]

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

[Samuel Michael]

Yeah in ruby had to do a lot of interesting metaprogramming

[Samuel Michael]

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

[Samuel Michael]

Thanks

[Samuel Michael]

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

[Samuel Michael]

I wouldn't imagine using it much personal ly

[Samuel Michael]

Can be fun and good for multiple dimensions and prototyping

[Samuel Michael]

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

[Samuel Michael]

Sure it could be open source
