The problem with Scala 3 is that nobody asked for it. The problem with Scala 2 is that the type inference part of the compiler is still broken. Nobody worked on that. Instead they changed the language in ways that don't address complaints. Completely ignore the market and deliver a product nobody wants. That's what happened here.

PS Perhaps they should make an actual unit test suite for their compiler. Instead they have a couple of dozen tests and have to guess if their compiler PR will break things.

You did not even try to formulate it in a way that could be interpreted as you just not knowing; instead you make blatant false statements in the most confident way possible.

Your statement is therefore an outright lie, spreading FUD.

As a matter of fact the Scala compiler has thousands, likely even tens of thousands of test cases.

But that's not all. Scala (2 & 3) has also a test case called "community build" where new compiler releases are tested by compiling millions of LOCs from all kinds of Scala OpenSource projects.
