The types for Set and Map are noisy in REPL

[som-snytt]

Reproduction steps

Scala version: 2.13.11

Welcome to Scala 2.13.11 (OpenJDK 64-Bit Server VM, Java 20.0.1).
Type in expressions for evaluation. Or try :help.

scala> Seq(42)
val res0: Seq[Int] = List(42)

scala> Set(42)
val res1: scala.collection.immutable.Set[Int] = Set(42)

scala> Map("a"->42)
val res2: scala.collection.immutable.Map[String,Int] = Map(a -> 42)

Problem

The types for Set and Map aliased in Predef instead of scala.package are noisy.

It makes it look like I accidentally summoned a type which is not the "default".

This issue is possibly different from "display shortest name given my imports".

reminds me of the business about whether to show Object or AnyRef. we would prefer the latter, but often we end up showing the former.

That's one way of looking at it, but it's also possible to think of it as the compiler helpfully showing you what the shortcut you used actually points to.

Yeah, I'd say those are distinct. One's about imports, one's about aliases.
