Hi Kisaragi,

This appear to be a bug in parifer-mode.

The following code

===
(if (fboundp 'save-mark-and-excursion)
    (defalias 'parinfer-save-excursion 'save-mark-and-excursion)
  (defalias 'parinfer-save-excursion 'save-excursion))
===

is evaluated at load time while the macro definition should be present
at compile time to be effective.  To obtain this the form in discussion
should be wrapped in an `eval-when-compile' to be effective.

You should be getting the same error byte compiling the file from a
fresh Emacs where this package was not loaded.

I'm closing this, feel free to link this discussion if you open a PR to
parifer-mode or reply to this if you need more info.

Thanks for reporting this!

  Andrea
