Description
See comment here
Lots of grouped operations together
@groupby df :a begin
@transform :a1 = mean(:a)
@combine :a2 = ...
end
This is speculative, and might never see the light of day, but I wanted to preserve the idea while closing the linked issue.

Research direction
Read the linked comment in issue #302 and review the existing @groupby, @transform, and @combine macro behavior before proposing an implementation. The issue is explicitly speculative and names no files, tests, or settled acceptance criteria, so a first step would be clarifying the desired syntax and semantics for grouped operations.
