To me, this is the most promising direction, but I’d suggest the use of “unwrap" as the keyword. If you compare these two:<br>
<br>
a) guard let foobar = foobar else { … }<br>
b) guard unwrap foobar else { … }<br>
<br>
I think that b) wins by virtue of eliminating repetition ("foobar = foobar" fails DRY principles), but retains clarity by introducing a word into the grammar that people already commonly know and use, and which is googlable if they don’t.<br>
<br>
</span>I find b) to be quite convincing.<br>
<br>
Best,<br>
