The thrust of the blog post was the stylistic question of whether to use <- or = for assignment, not a recommendation to use constructs like this. (In fact, the next line reads "This is a contrived example though, and never really occurs in real-world programming.") But I've added your sound advice that such constructs are best avoided. I've never seen the need to perform assignments in function calls before, but I'll avoid them now knowing about potential for mischief from lazy evaluation.
