The presence of autoloading trigger keywords can be overridden using
:demand t, which forces the package to load immediately. Thus,
even if you use an autoloading keyword such as :bind
(see Key bindings), adding :demand will force loading to
occur immediately. It will also avoid creating an autoload for the
bound key, as it would be redundant.
If you specify both :demand t and :defer t, the
:defer keyword will take precedence.
