Sounds interesting, but I must be missing some context because there's
a lot of references I don't understand.  Could you expand on them?

No idea what you're talking about here.

Oh... wait, are you talking specifically about completion in code
buffers, so "symbol name" above referred to the ability to complete an
identifier?
As for this "extra info", I see what you mean, but usually completion
involves several potential candidates, so listing them all plus all
their info would take way too much space in general (if not, then
something like completion-annotate-function should work).  So usually
this extra info is provided outside of the completion functionality
(e.g. via eldoc-mode or something similar).  But, yes, I'd like to
extend the *Completions* buffer so that you could ask for more info
(either on all entries, or just on one at a time).

No idea to what this is referring.

Idem.  Unless you mean something like skeletons/templates, but then
I fail to see the connection with completion.
