Each entry in the alist is a list of three elements. The first
element is the `use-package' keyword and the second is a form
that can be evaluated to get the default value. The third element
is a form that can be evaluated to determine whether or not to
assign a default value; if it evaluates to nil, then the default
value is not assigned even if the keyword is not present in the
`use-package' form."
