@Iaroslav Postovalov just published an article about AST-based optimization of mathematic expressions in Kmath: https://medium.com/@postovalovya/expression-optimization-with-jvm-bytecode-generation-b50304b96619. It is a little bit technical, bur I think it worth reading for people who are interested in performance on JVM.

@Iaroslav Postovalov Did you look at invokedynamic at all? It allows for doing things like specialising call sites or call targets to avoid boxing

[Iaroslav Postovalov]

Yes, it is a great idea. However, currently, I do not quite understand how to create an object that has context-dependent behavior, or make bridge method return not an object (without using Java 11 on which I don't need any bridges)

[Iaroslav Postovalov]

And, of course, I know about invokedynamic and lambda metafactory

[Iaroslav Postovalov]

And I'll check if I can use altMetafactory to implement behavior you were about.
