Enable inline classes

[Wasabi375]

I know I read it somewhere but I can’t find it. How do I enable inline classes again using gradle. Right now I just get this error

The feature “inline classes” is experimental and should be enabled explicitly

but I can’t find anywhere how I enable this feature. I guess it is something like you do with coroutines

kotlin { experimental { coroutines 'enable' } }

but I can’t find the required flag for inline classes.

Kotlin 1.2.60 Early Access Preview

Inline classes are actually a feature of an upcoming 1.3 (Inline classes · Issue #104 · Kotlin/KEEP · GitHub), which is being developed in the master branch under a separate compiler argument for simplicity. You can enable the feature with the compiler argument -XXLanguage:+InlineClasses. Note that this will mark your compiled code as “pre-release”, so that it’d be impossible to use it as a library when using “release” Kotlin versions (less than 1.3 at the moment).

mmm. Could have sworn it was already part of 1.2.5. Sadly 1.2.6 does not work with serialization yet so, no luck for me.
