Three Months of Go, from a Haskeller’s perspective (2016)

> How robust/mature is it as of yet? More importantly, how are compile speeds and how much of a priority are they to the compiler maintainers? I too find it quite promising in terms of "a language aiming for the benefits of Go with the expressiveness and added easier correctness of FP".

I never get the compile time argument. Well I code a big Scala application and the most time it spents is integration testing. the 10 minute test suite would probably still run 9 minutes and 30 seconds on go. we heavily rely on the database and cover a lot of concurrency/parallelism things in our tests. some things which we would need to test in go, too.

the compile time argument always looks good on first, but later on it's just a dumb way to prefer a language since it never matters. (Actually even the go maintainers didn't cared for a while about the compiler performance).

Well, the thing is, with compile times of 2 seconds I can run my unit tests as fast as possible. At the same time, I'd just use a mock database for most of the tests.

It's great to be able to compile applications like kubernetes in 2 minutes.

If compile time is an issue, the new 'cargo check' tool may take some of the pain away.[1]

More to the point, Rust is trying pretty hard on the compile time front. They've almost got incremental compilation out the door, on top of this.

Does kubernetes take 2 minutes to build? That seems super long. I csn compile juju (1mil LOC) in like 15 seconds.

I haven't compiled it myself but I've read it's something like that. Though I'm not a 100% sure.

with all dependencies (first time compiling) it takes way longer than 2 minutes.
