Timo Walther commented on FLINK-1062:
-------------------------------------
Thanks for you example. I already implemented this part in a similar fashion
yesterday, but e.g. without using the symbol "SerializedLambda" for backwards
compatibility. I will open a PR tomorrow, than we can discuss the entire
solution.

> Assignee: Timo Walther
> Fix For: 0.7-incubating
