Thank you for the suggestion. However, I don't believe there's any serious
demand for this feature, to justify it being included in core.
In fact, `does AutoFail[X::NYI, "Sorry, we haven't gotten to foo yet!"] ` is 1
MORE characters to type than `die X::NYI.new: :feature<Sorry, we haven't gotten
to foo yet!>`
Perhaps, you could publish it as a module:
