Done and done.

I agree, I've removed it.

Done.

Fixed.

I ended up moving to this structure and changing the pcase to a
pcase-let which I think makes things a bit cleaner, let me know your
thoughts.

I believe I have the type correct for the new layout.  For example the
following renders correctly:

(setq org-agenda-bulk-custom-functions 
      '((?a ignore)
	(?b ignore nil)
	(?c ignore ignore)))

Side note I'm not sure your example would render properly regardless
since `my/bulk-action' and `my/args' aren't functions.

Cheers,
Kevin Foley
