Hi! I just looked up this bug after running into this warning. Thanks for your work on all this @cosmicBboy Can we make it so that on DataFrameSchema __init__, the...

I could do a PR for this. That change to `Column.set_name` would be breaking for users. Do you want any sort of warning or deprecation schedule? ie leave it as...

Good thought, don't know for sure, but looking at the source code my impression is that it will always have overhead. To get around this we could write our own...
