Description of the problem:
Useless closing bracket.

As an independent exercise, look at the docs for the types as well as the std::pin module and try to work out how you’d do this with a Pin wrapping a Box.)

Suggested fix:
Remove the closing bracket right after Figure 17-6

As an independent exercise, look at the docs for the types as well as the std::pin module and try to work out how you’d do this with a Pin wrapping a Box.

Open src/ch17-05-traits-for-async.md and read the section around Figure 17-6 and the Pin and Unpin traits. Remove the closing bracket after Figure 17-6, then check the rendered section to confirm the exercise text ends without the extra bracket.
