Agreed with the exception that I'd like to review whether the forward reference to dict in the tutorial might be better suited to people working thru the tutorial than the current forward reference to the real docs.

I got to take a look at Eric Matthes' excellent "Python Crash Course".  He avoids this by treating function definitions only after introducing both tuples and dicts, rather than together with simple control flow within a function.  That would clearly be a re-org that is way out of scope of a bug report.

So, if someone compares the potential forward reference to the dict section of the tutorial rather than the current forward reference to the language reference in light of where the tutorial audience is expected to be at when reading this section, I am good with closing it.
