The reasoning here is pretty straightforward: you don't say "Hungry, if
eat." That doesn't make sense. We want to get "foo" back if given
"fizz", so it seems this makes far more sense as "Eat, if hungry," or in
this case, return `foo_if_fizz` is given.

Instead of having to explain why
```rs
let mut x = 100;
let y = &mut x;
let mut z_owned = *y;
let z = &mut z_owned;
*y += 100;
*z += 1000;
```
and
```rs
let mut x = 100;
let y = &mut x;
let z = &mut *y;
*y += 100;
*z += 1000;
```
are different, you still get the point across about having only one mutable reference.
As it stands, this exercise does too much (dereferencing and having only one mutable reference), and by doing so confuses people.
Example of someone being confused by this:

fix(from_str, try_from_into): custom error types
...
Remove the use of trait objects as errors from `from_str` and
`try_from_into`; they seem to have caused a lot of confusion in
practice. (Also, it's considered best practice to use custom error
types instead of boxed errors in library code.) Instead, use custom
error enums, and update hints accordingly. Hints also provide
some guidance about converting errors, which could be covered
more completely in a future advanced errors section.
Also move from_str to directly after the similar exercise `from_into`,
for the sake of familiarity when solving.
