But what percentage of "real world" functions work on completely generic types? In reality most useful functions take more specific types, and those types allow many more operations to be performed on them. In general, it's not really possible to tell what a function does just by looking at the type signature.

You aren't forced to go straight from fully generic types to specific types. That is the entire point of type class constraints which give you fine grained specification of behavior.

Define "real world functions" :)
