Please move this assertion out of the immediately executed lambda expression --
let's keep it as simple as possible.
Also consider adding something like `&& "This function should always be called
with a canonical declaration."` because IMO this would be helpful for a reader
(who otherwise may have thought about a more fundamental reason for asserting
this).
