## Reproduction steps https://www.scala-lang.org/api/current/scala/collection/mutable/Buffer.html#padTo[B%3E:A](len:Int,elem:B):CC[B] ## Problem It's growable & shrinkable, but growing methods should call it growable. There is a ticket for nuanced CC vs C or something, so it is probably the same effort to chisel how collections refer to themselves in doc macros.
