We don't necessarily need to do the same, but for reference here's how Java does it: http://www.benf.org/other/cfr/switch-on-enum.html, it's complicated because it's designed to survive reordering and addition of fields to the enum.
This is a must done,take a look at :
https://github.com/akka/akka/pull/25982/files#diff-ac929e6fd84743df4b6e214b5499d644R423
for why...
@hepin1989 without benchmark results you won't convince us that it's a "must done"
Same patterns in scala future,zio, etc
and we can't rely on mima because definitions are order sensitive
Just following up on a conversation @odersky and I had at SBTB … I was wondering if we could use enum ordinals to emit tableswitches for eligible
match
expressions. I have had cases where I had to reorder cases as a performance optimization and something like this would have been really helpful.
