String Dynamic Abbrevation (DAbbrev)

[Nordlöw]

Would it be convenient if dabbrev-expand worked for strings aswell?
I believe such a function must need a separate key-binding to
distinguish it from the real dabbrev-expand that of course can be
performed the words the string content is built up of.
I miss this feature especially often when using assoc() in elisp
coding.
Mayby the template mechanism could give hints to such a function.
I then believe dabbrev-expand-thing-at-point should a good name for a
function merges all these logic into one interactive function and upon
call asks the user for the expand scope: literal, string, sexp, etc.
