Seq(LazyList(2), Vector(3)) return too complex type in Scala 2.13

similar issue #7402 (fixed. 5 years ago)

Similar to my comment on #10907; yes, this is an issue, but only indirectly related to the new collections.

😱

Welcome to Scala 2.13.0-pre-9bfd7d8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_181).
Type in expressions for evaluation. Or try :help.

scala> Seq(LazyList(2), Vector(3))
error: Error while emitting 
Maximum String literal length exceeded

LUB of F-bounded types with refinement = 😱

scala> println(lub(typeOf[LazyList[Int]] :: typeOf[Vector[Int]] :: Nil))

I guess all those methods in the refinement come from SeqOps. If we remove AbstractSeq we get just Seq[Int] because Seq[+A] extends SeqOps[A, Seq, Seq[A]]. But it's not possible to have AbstractSeq[+A] extends SeqOps[A, AbstractSeq, AbstractSeq[A]] 🤔

[joroKr21]

How about having trait TheOneAndOnlyAbstractSeq[+A] extends AbstractSeq[A] with SeqOps[A, TheOneAndOnlyAbstractSeq, TheOneAndOnlyAbstractSeq[A]]? Would this nullify the class size benefits of AbstractSeq?

in #11883, @OlegYch found a case where a relatively short piece of code takes 30 seconds to compile because of this issue

the workaround, of course, is to add an explicit type

In Dotty:

scala> Seq(LazyList(2), Vector(3))
val res0: Seq[scala.collection.immutable.AbstractSeq[Int] & Serializable] = List(LazyList(<not computed>), Vector(3))
