In Python, where ||= works, I do use that from time to time because it’s “idiomatic”, but I don’t really think it’s very obvious what it does. In Swift, my programming style is a bit different, and I don’t find myself needing it. Especially due to the way it keeps optional (which is obviously not an issue in Python).</div><div><br></div><blockquote type="cite"><div><div style="word-wrap:break-word"><ul style="padding:0px 0px 0px 2em;margin-top:0px;margin-bottom:16px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,'Segoe UI',Arial,freesans,sans-serif,'Apple Color Emoji','Segoe UI Emoji','Segoe UI Symbol';font-size:16px;background-color:rgb(255,255,255)"><li>Does this proposal fit well with the feel and direction of Swift?</li></ul></div></div></blockquote><div>I don’t know, but I don’t think it’s a very important addition and can lead to confusion instead.</div><div><br></div><blockquote type="cite"><div style="word-wrap:break-word"><ul style="padding:0px 0px 0px 2em;margin-top:0px;margin-bottom:16px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,'Segoe UI',Arial,freesans,sans-serif,'Apple Color Emoji','Segoe UI Emoji','Segoe UI Symbol';font-size:16px;background-color:rgb(255,255,255)"><li>How much effort did you put into your review?
