Can I call a task from within another task? Is this allowed? Bad style? No problem at all? Any caveats? I suppose its problematic because this could take the A out of DAG…

Yes you can. But the task inside will not show up in the DAG. Is it bad style? Not sure.

Naaa, its more of a "if A then do g(f()) else f()" situation. But i can rewrite it to work with return values and

case()

. Or maybe

apply_map()

, yes. Thanks.
