[jira] [Commented] (BEAM-14397) Support type hinting generics in Apache Beam type inference

    [ https://issues.apache.org/jira/browse/BEAM-14397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17540860#comment-17540860 ] 

Valentyn Tymofieiev commented on BEAM-14397:
--------------------------------------------

Also:  if Iterator is imported from collections.abc instead of typing (to annotate process() of DoFn classes), then Beam does not consider it to be iterable.
