until will get an intrinsic in 1.1.4 https://youtrack.jetbrains.com/issue/KT-9900

[elect]

would it be possible also for repeat?

[ilya.gorbunov]

What is the issue with repeat?

[voddan]

the only problem with intrinsics for library functions is that it becomes an expert knowledge what gets optimized and what not.

[damian]

repeat will already be fully optimized. it's always inlined and it takes advantage of the .. intrinsic

[elect]

nice to hear

[elect]

I am really interested in knowing what's optimized and what's not

[elect]

I'd like to read a deep and full report on Kotlin

[elect]

for example, I read once an article showing that forEach was much slower than a simple for

[voddan]

forEach was much slower than a simple for

That's because forEach is a generic function and has to use a generic iterator

[voddan]

I am really interested in knowing what's optimized and what's not

Maybe we need to keep a list of all intrinsics and compiler-level optimizations on kotlinlang.org

[elect]

that'd be awesome!

@elect make the first PR to the site, others will follow 😉
