In code like let x = 5, I am initially confused as to the meaning of "let doesn't take a name on the left hand side, it actually accepts a pattern." - I interpret that as the pattern being located as: <pattern> let [...].

I think what is meant is that the name/pattern is on the left hand side of the assignment, rather than to the left of the let statement. This change clarifies that.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @huonw (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

I think what is meant is that the name/pattern is on the left hand side *of the assignment*, rather than to the left of the *let* statement. This change clarifies that.
