Move scala.internal.quoted to scala.quoted.internal?

[smarter]

If we could avoid adding even more stuff inside scala that would be great, and there's nothing else in scala.internal, wdyt @nicolasstucki ?

[smarter]

There's also a dotty.internal which only contains CompileTimeMacros, could that one be a private object where it's used instead?

[nicolasstucki]

Adding it an internal to quoted would mean that each time we import scala.quoted we would import internal. This would not be ideal.

[smarter]

But the compiler adds import scala._ to all Scala files automatically, so we're already importing internal.

[smarter]

The alternative would be to keep the internal stuff as package private in scala.quoted

[nicolasstucki]

Patterns and PickledQuote could fit as package-private in scala.quoted. I'm not sure about CompileTime.

internal.quoted.{Expr,Type} classes exist to allow quoted.{Expr,Type} to have private[scala] constructors. In theory, we could implement those in the compiler but we cannot do it because the compiler is not in the scala package. Maybe we should move the compiler root package dotty to scala.tools.dotty and follow the same naming scheme as in Scala 2 (scala.tools.nsc).
