[jira] [Commented] (CALCITE-2186) Implement ScalaTypeFactory

    [ https://issues.apache.org/jira/browse/CALCITE-2186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16368338#comment-16368338 ] 

Julian Hyde commented on CALCITE-2186:
--------------------------------------

Or possibly add this functionality to JavaTypeFactory. Such patterns will never occur in Java programs, only Scala, but that shouldn't concern the type factory.

> It would be useful to have a ScalaTypeFactory which would work out of the box for case class parameters list.
> Possibly it could be extensible to support via extensions with some common Scala record patterns like HList's, tuples and similar.
