Perfect!

Only one detail:

| @@ -71,12 +79,14 @@ map-let
|  KEYS can be a list of symbols, in which case each element will be
|  bound to the looked up value in MAP.
|
| -KEYS can also be a list of (KEY VARNAME) pairs, in which case
| -KEY is an unquoted form.
| +KEYS can also be a list of (KEY VARNAME) pairs and
| +\(KEY VARNAME DEFAULT) triples, in which case KEY is an
| +unquoted form.

Here you could also say that DEFAULT is an unquoted form.

The rest looks good to me.


Thanks,

Michael.
