Preferred way to mark a method as deprecated

Does Ruby have built in functionality or a convention for marking a
method as deprecated? Something like ActiveSupport’s deprecate method
is what I have in mind, but more general.

Add ‘warn “blah is deprecated and will be removed”’ as the first line
of your method.

There’s no need to complicate anything with extra methods you have to
call.
