Probably the same kind of place that bans use of the ternary conditional operator because it's "too complicated" <sigh>
Eh, I can't say that I have any love for the ternary if operator. It is an ugly construct made necessary by the other flow control constructs being statements. Scala lets you just use if/else like that, the result is much clearer at the cost of 4 or so characters.
Guilty as charged. Although it's practically the same, I prefer the TRUE part. Same with the !aBoolean and FALSE.
I saw this in some coding standard for PHP.
Where it actually makes sense (assuming === and not == is used for comparison).
