Right, thank you.
Apparently, the long-standing way to make it work is to call
visit-tags-table with non-nil second argument, instead of just using
setq-local. So, this seems to work correctly:
(visit-tags-table "~/examples/ruby/TAGS" t)
It performs more work in advance, though, and I'm not sure what's the
big picture with keeping variables like tags-table-list global anyway.
Here's a patch you can try that makes etags--xref-find-definitions work
with your original scenario, but I'm not 100% sure it's good code. The
proper solution to setting tags-file-name locally probably looks different.
