Description
New feature
Hi,
I am trying the new typed operators (which are awesome) and I think a great enhancement would be to allow using the groupBy operator on a channel of records. Currently, it is only available for tuples.
Thanks a lot!

Research direction
Start by locating the typed groupBy operator implementation and its tests, then compare the existing tuple handling with record values. Confirm how records with a specific key are represented and add coverage for grouping them. Done means groupBy accepts the requested record input while preserving existing tuple behavior.
