I am an advanced programmer. I shouldn't have to read code snippets to figure out if a function returns a tuple or a 'group' which can be iterated over, but can't be indexed. This is something which would be fixed if the documentation included types, because then I could check what all the allowable operations on 'group' are directly without searching for a code snippet which does what I want or just running it and praying I got it right.
