in thread ?: = Obfuscation?

I like ?: when the args are short.

I spent years as a LISP programmer. A programmer who has memorized the precedence table will write code that's understandable by others who have memorized the precedence table. Use parenthesis liberally.

$longways = $widthIsLonger ? $width || 1 : $height || 1;
may work and is terse, but
$longways = $widthIsLonger ? ($width || 1) : ($height || 1);
reads better to me.

It's mostly the case that if I'm using an operator within the scope of ?: I'll parenthesize.

[Tanktalus]: yeah, I saw you post about MCE - the concept looks really really cool. I wonder how well it plays with Coro :)
[Lady_Aleena]: Hi guys. I asked this earlier but got no answer. Why is this dying at -exec: my @music_times = qx(find ~/Music/Albums/ -type f -iname '*.mp3' -exec mp3info -p "%S\n" {} \;);
[Lady_Aleena]: The error find: missing argument to `-exec'
[Discipulus]: Tanktalus we will be glad to have you here more frequently, tho ;=)
[marioroy]: Lady_Aleena oh I thought you found the error by adding -exec mp3info
[Tanktalus]: Discipulus: I should be working on an interview test right now. Well, I kind of am, but keep getting myself distracted :)
[Lady_Aleena]: marioroy, nope, that IS the error.
[Discipulus]: oh to be distracted PM is still a wonderfull place
