Consider two versions of setting xiakos. The let defines local bindings.
Can the let block be placed outside a defvar or inside. Does it make a
difference ? Although defvar is used to define global variables, can it
be used to evaluating local bindings like let ? Which version would one
suggest ?
(let ( (orella-waypt
(questor-path-snip marshal-waypt "orella")) )
(defvar xiakos
`( ("GLXKS" . ,(concat orella-waypt "/xiakos"))
("GLXKS" . ,(concat orella-waypt "/xiakos")) ))
and
(defvar xiakos
(let ( (orella-waypt (questor-path-snip marshal-waypt "orella")) )
`( ("GLXKS" . ,(concat orella-waypt "/xiakos"))
("GLXKS" . ,(concat orella-waypt "/xiakos")) ))

I'd place the `let' inside the `defvar', because it makes it easier to
evaluate the value manually without changing the value of the variable.

Can you clarify what you are talking about ? What would one want to evaluate ?

In my experience, as a general rule it is better to make scopes as
small as possible.
I'm also curious why you're using a defvar at all.
