Yes. I guess `rename` should allow arbitrary expressions in the RHS so that you can do ``` @rename df :newcol = begin "old_col" * "1" end ``` and of course...
No. see the `:newcol = ...` at the top, it would be equivalent to ``` rename(df, ("old_col" * "1") => :new_col) ``` `@rename` should only ever create a `rename(df, a...
The error above is because all the old names need to be the same type and all the new names need to be the same type. Just cast everything to...

oh wait, it *is* sorting the tuple lexicographically. But within this it's sorting the arrays lexicographically. This is "right" in the sense that it's behaving as Julia behaves, but it...
Okay I'm back. Here's whats going on. The transformation ``` ([:b, :a]) => ((bat, falcon)->(falcon, bat)) ``` creates a tuple of vectors. Because a `tuple` of vectors is functionally a...
Yes, exactly.
