Ah...you just linked to the section on constants where all the various
incarnations are subsections.

It would be a nice addition to include some examples in the section
pertaining to escape syntax. Make it more clear how it differs from just a
non-escaping literal. Maybe put something like \n into the basic literal
section showing that it outputs the literal two characters instead of a
newline.
