2021-02-16	Document that `assert!` format arguments are evaluated lazily	Teddy Katz	-0/+11
	It can be useful to do some computation in `assert!` format arguments, in order to get better error messages. For example: ```rust assert!( some_condition, "The state is invalid. Details: {}", expensive_call_to_get_debugging_info(), ); ``` It seems like `assert!` only evaluates the format arguments if the assertion fails, which is useful but doesn't appear to be documented anywhere. This PR documents the behavior and adds some tests.
