Whenever a temporary is created, it is automatically dropped (freed) according
to fixed rules. Ordinarily, the temporary is dropped at the end of the enclosing
statement -- in this case, after the `let`. This is illustrated in the example
above by showing that `tmp` would be freed as we exit the block.

There are four lets in this file, two in the first example and two in the second example. I think "after the let" refers to the first let in the first example, but you've updated this as if it's referring to the first let in the second example? Also, you've said "outer let" but there isn't an inner let.

I suggest just changing "after the let" to after the let p` in the first example above". What do you think?

So if you count the let tmp = foo(); on line 25 as one then there are five lets, and this one is the "inner let" that I was implying existed, and this is the let that I initially thought the line in question was referring to, but either way, I agree that adding in the "outer" wording is confusing since the second example is really just used to explain what's going on in the first example. I think just making it read:
"after the let p statement"
would be sufficient because then you can refer back to either of the two examples and it's valid.

To fix this problem, you need to create a local variable to store the value in
rather than relying on a temporary. For example, you might change the original
