The TYPE parts all simply look like

  (val my-command-register)

where my-command-register is defined with `cl-defstruct'.

Some definitions are wrapped in a lambda and pushed to
`after-init-hook' using this macro:

(defmacro after-init (&rest args)
  `(add-hook 'after-init-hook (lambda () ,@args) 'append))

The others things are top-level definitions.

Will answer that when it happens the next time.
