They're short so they're quick to parse (for a human) and read.
They're easy to type. If you have a constraint like (Eq a,Num a,Ord
a,Show a,Ix a) you can see all five type classes at a single glance
without having to scan your eye across the line. They're highly
mnemonic in the sense that once I'd learnt what they meant it became
hard to forget them again. What exactly is wrong with them?
