That would be a helpful temporary measure for people, but I suggest that 
additional work to do this better is appropriate.

It's conventional for the non-body parts of a form like this to be 
indented more than the body forms if they appear after the first line, 
to distinguish them from the body.

If we just add "let:" to "Lambda-like Keywords", then parts of a 
named-"let:" after the name are indented as if they are body forms.
