# coroutines

[irus]

I already use coroutines in production, experimental is not an issuer for me, ans I listen @elizarov's talk at GeekOut where he say that you should use coroutines in production . But I giving a talk tomorrow at GDG DevFest Kaliningrad, and pretty sure that I'll receive question about 'experimental' status of coroutines in 1.2. And according Kotlin 1.2-M1 blogpost comments, coroutines will save status 'experimental' in 1.2 release.
