@HyukjinKwon ,this pr started with a 'rewrite' of struct into named_struct
(in order to fix an analysis bug), it later evolved into a complete removal of
CreateStruct. I guess we did think about the pretty print representation of the
tree (after all any analysis/optimizer change results with a different tree)
but we didn't think about the way it affects names of 'anonymous' columns
-which is exactly what happens in this case.
