I maintain — they shouldn't be fancy. ‘Fancy’ is the mark of something your language doesn't support well. They can be _long_, and that's often worth breaking up, but if something is ‘fancy’ it's because it's not clear to read, so you should attach some identifier to it that explains what it's supposed to mean. That's significantly, though not exclusively, a function (ha) of the syntax used to express the concept.
