Despite D is currently not widely used, it's not hard for me to find references
about D into computer science papers I find around.
This paper is titles "Code Sandwiches", by Matt Elder, Steve Jackson, and Ben
Liblit, it discusses D scope guards too (page 7 and several successive pages):

One of the things the paper says about D scope guards is: "Scope guards do not
provide encapsulation".
Indeed, they are not related to encapsulation directly. What they do
provide is a convenient way to write exception safe code, with less fuss
and bugs. It's a practical "shortcut" feature meant to be used inside of
encapsulated entity, not to create or support one.
