[jira] [Commented] (BEAM-324) Improve TypeDescriptor inference of DoFn's created inside a generic PTransform

    [ https://issues.apache.org/jira/browse/BEAM-324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15949417#comment-15949417 ] 

Daniel Halperin commented on BEAM-324:
--------------------------------------

[~bchambers] -- I know we've made some more improvements e.g., SimpleFunction with Lambdas. Any specific work remaining, or open as a wish list item?

> Commit https://github.com/apache/incubator-beam/commit/aa7f07fa5b22f3656d52dc9e1d4557bceb87c013 introduced the ability to infer a {{TypeDescriptor}} from an object created inside a concrete instance of a {{PTransform}} and used it to simplify {{SimpleFunction}} usage.
> We should probably look at using the same mechanism elsewhere, such as when inferring the output type of a {{ParDo}}.
