The following code computes fibonacci(35) where each worker reads from a channel of repeated 35’s, and writes the answer to a channel, the main task reads from the answer channel....

Implement the main part of the xref interface

For the xref interface see https://github.com/emacs-mirror/emacs/blob/master/lisp/progmodes/xref.el, and the lisp xref backend in https://github.com/emacs-mirror/emacs/blob/master/lisp/progmodes/elisp-mode.el This implements `xref-find-{definitions,references}`. It's not quite perfect -...
