geiser-edit-symbol-at-point (M-.) does not work on
fork+exec-command. geiser wrongly tries to lookup fork instead of
looking up fork+exec-command. This is because (thing-at-point 'symbol)
does not correctly identify the whole symbol. And, that, in turn, is
because ?+ has been reclassified as an expression prefix character (')
in .dir-locals.el. It should be a symbol constituent character (_) which
is the default for scheme mode.
(modify-syntax-entry ?+ "'")
This is a rather trivial bug. But, I thought I'll just document it
here. I'm not sure if we should fix it. I can't think of any easy way
out.

What about proposing this change to ‘scheme-mode’ to Emacs upstream?
Alternately, or in the meantime, we could carry that fix in Geiser
maybe?
Thoughts?

I don't think reporting this to scheme-mode or geiser would help. They
are justified in classifying ?+ as a symbol constituent character
(_). It is we (the Guix project) who have reclassified ?+ as an
expression prefix character (') in a "non-standard" way for our use in
gexps. WDYT?

Oh true, sorry!
Well I don’t know, I’m confused now. I vaguely remember prior
discussions about this with Alex Kost, but I forgot what the conclusions
were. :-/
