<div dir="ltr"><br><div>I just noticed that in the Racket Guide Chapter 13 "Classes and Objects" where they discuss interfaces they don't use the convention of ending an interface with <%>, i.e. they have "fish-interface", "grower-interface" ... not "fish-interface<%?" etc. The Racket reference chapter 5 does use the convention of ending with <%> but as far as I can see they don't say it is the convention. I vaguely recall that the convention of ending interfaces with <%> was mentioned (still is?) somewhere in the documentation in the past.</div>
