What about compilation times (for those tests that can be compiled on both)?
Scala 2 and Scala 3 have overlapping test suites, but I tried compiling all the Scala 2 tests and all the Scala 3 tests with *both* compilers. 3103 tests compile and 2190 (correctly) don't compile with both compilers. But 1044 fail only with scalac and 1024 fail only with dotc.pic.twitter.com/jN4LNjkk2J

I didn't check, but it would be interesting to try. I'll do that some time. Unfortunately, Scala 3 doesn't support -Xresident, so I have to launch a cold new JVM every time.

This only reassures me in fact that state of the world for Scala 2/3 would be as bad as it is for Python 2/3.

Bear in mind that these are the tests for the language, so they're not representative of typical code. And they're compile errors, not runtime exceptions!

Wondering how many will misread those numbers...

Someone misinterpreting something on the internet? Never!

Did you get them both to compile with fury yet?
-
The compilers themselves? Not yet... but it will be possible. Probably Dotty first.
