* Update unit tests to use generic perimeter
* Update solution to use perimeter
Update solution to use the generic term perimeter instead of circumference
* Corrections around slices and string slices, also slight improvements to the language.
* Explained some of the confusing details in the functions example.
* Added a speaker note (hinting at `Into` as a complement to generics).
* Exclude the clarification code snippet from build testing.
* Update functions-interlude.md
Do not mention explicit section numbers as they may change.
* Update string-slices.md
* Adding an extra example of converting `String` back to `&str`.
* C++ who would often read this guide could get immediate intuitive understanding of Rust strings if you compare them to C++ equivalents.
* Expand on `String` vs `std::string`

* Update lifetimes-function-calls.md
I am trying to describe the problem lifetimes solve. It may seem they are complex and useless, but the paragraph starts from the problem Rust cannot
solve on it's own (yet). Then the paragraph illustrates the problem represented in the code and how lifetimes solve it.
* Update lifetimes-function-calls.md
Moving the generic explanation of why lifetimes are important to the speaker notes.
* Make language more direct

* Update mutex.md
Adding speaker notes why Rust `Mutex` has its design and mentioning briefly `RwLock`.
Someone from the audience can notice `unwrap()` in the code, it might be worth to have the answer in speaker notes.
* Apply suggestions from code review

* Update channels.md
Adding speaker notes explaining why `send` and `recv` can fail.
* Explicitly mention that the channel is closed when the sender/receiver is dropped

* Update result.md
Adding a speaker note that `Result` documentation is a recommended read.
* Adding a note why `Result` encourages error checking.
* Wordsmithing

* Update iterator.md
Adding a Speaker Note emphasizing that all most all functional programming toolbox over collections can be found in the `Iterator` documentation.
* Wordsmithing

* Update match-guards.md
Adding more information how match guards are different from simply using "if" inside of the match case, after the case has matched.
* Be consistent about naming of match arms.

* Update box-recursive.md
Adding Speaker Notes. This is a high-level guideline what to say, so we can settle on one explanation and review it.
This may be very obvious with the background in some languages, but be very non-obvious in languages that always
use references and never embed structs into structs.
* Fix wording
Co-authored-by: Andrew Walbran <qwandor@google.com>
* Update if-expressions.md
Adding a note about types of `if` branch blocks.
* Fix typo and simplify.
