A modern programming language that makes developers happier.

kotlinlang

1.  A simple histogram of elements given a list of stuff. I end up doing this usually
```some_stuff.groupBy { it }.mapValues { it.value.size }```
Which works but feels a bit silly from a couple of angles

this was discussed in today's thread: `some_stuff.groupingBy { it }.eachCount()`

yeah, I'm aware of groupingBy as well, will be a bit faster I guess

I'll probably add my own extension function then

I usually find it silly when I have to write `{ it }`. In this case a small wrapper function (e.g. `grouped()`) would be nice. It’s just much more readable in particular when in a nested lambda (e.g. flatMap)

I like the syntax with Arrow's `identity` fonction: `groupingBy(::identity)`
