@altavir what are the big disadvantages of JNI anyway? Besides debugging inconvenience and weird overheads outside the JVM? 🤔 the more I watch you toil at this and deal with boxing the more I wonder if we truly are making this BLAS thing difficult.

What we really need for that is a seamless Kotlin-JVM - Kotlin-native bridge. Which will internally generate JNI boilerplate.
