Hello @valhalla-dev <valhalla-dev at openjdk.org>,
I have spent the past week or so playing around with the JEP 401 EA,
gathering a bunch of data. I am nearing completion with the data-gathering
phase, and preparing myself to start writing my experience.
However, I wanted to confirm what type of experience report is wanted for
this JEP 401. It's been mentioned in multiple places that many of the
performance optimizations one would come to expect with Valhalla have yet
to be implemented yet. Understandable -- this is still just the EA of JEP
401.
So does that mean that experience reports should avoid talking about
potential performance increases/decreases? Or should we focus on the
usability and ergonomics of the language feature? Or is this just a typical
experience report, where we just speak freely about what did and didn't
work when trying on a real world program?
I'll post this thread to reddit once receiving answers. That way, others
who see that post will be able to format their experience reports
appropriately as well.
Thank you for your time and help.
