`:load-path` value has to be either a string or a function #1010

:load-path with a string value works as expected.

However, with a normal expression it causes Lisp error: (void-variable expand-file-name):

(use-package my-package :load-path (expand-file-name "config/my-package" (file-name-directory load-file-name))

While wrapping the same expression in lambda works:

(use-package my-package :load-path (lambda () (expand-file-name "config/my-package" (file-name-directory load-file-name))))

I think this is behaving as documented, and I'm not sure how to separate :load-path (foo bar), where the variables are foo and bar, and the case where you are calling the function foo with bar as an argument. So I think wrapping it in a lambda is the best we can do here, and I'm closing this issue.
