geiser-xref-callers (as most geiser functions), work by asking the guile
process for the callers, so it's unlikely syntactic obfuscation is an
issue directly.  but maybe some sort of delayed evaluation could play a
role, i am not sure.  just to make sure (i guess i already asked this in
those threads), you have loaded the module in your running REPL process
(e.g., with C-c C-k in the buffer), right?

if so, a way to look for more info is to enable full traces in geiser
with C-u M-x geiser-show-log, and see what pops up in the message's
buffer when you try the callers command.
