The expression functions have nothing to do with the readability issues 
here, it is intentionally confusing use of case and if expressions (that is, 
conditional expressions). These aren't the same thing, you know.

I'd have had more sympathy if you had commented on conditional expressions; 
I do think you have to use them carefully in order to avoid a mess. (But 
avoiding them can easily lead to a bigger mess, such as the idioms for 
writing static expressions that effectively contain conditional 
expressions.) But that has nothing to do with expression functions.
