Shopify invests in research for Ruby at scale

Thanks to generics, assuming there is some stream/sequence like type

    records := Stream.Limit(User, 10)
    records.Select(func(user User) bool {return user.IsAdmin()}).Map{func(user User) string { return fmt.Sprintf("%d %s", user.id, user.name) }

Yes a bit more verbose, that is the price to pay for static typing without full type inference as in the ML language family.

It blows my mind why Go didn’t have generics at launch. I suppose they just didn’t want people to be able to have abstractions like this at all?

oh wow thanks for this. I haven't been actively using Go since around the time this was written so I've missed it

Stream.limit and Stream.select(…).limit are not the same thing :)

records.collect({case u if u.isAdmin => s”${u.id} ${u.name}”}).take(10) guess the language

Well you can argue semantics, it doesn't change the fact that it is possible to implement the same concepts in Go with generics.

That line of code could be Scala, or something else.

In any case, the point is that there are compiled languages that offer similar productivity like Ruby, with AOT/JIT compilers out of the box, and great IDE experiences.

It is Scala. I meant to demo type inference and pattern matching. I know pattern matching(something I cant live without) does not exist in Go and Ts, not sure how well type inference works in Go
