I have a dataset which I use as "dsall" and a function keylist (just for my convenience, nothing spectacular):
keyList[ds_Dataset] := Keys@ds[[1]] // Normal // Flatten
Now I get the shadowing warning as shown in the picture. I get this only sometimes, even when starting from a clean kernel. Is there any idea where this comes from and how to avoid it? There is no symbol "data" in my context??
