I'm not sure what you mean there : genericLength is just a length that
can return any Num (eg. an Integer) and not just Int, it has nothing
to do with what Andrew wanted, which was a function that checked if a
list was longer than n without swallowing more of the list than
necessary.
Is there something I misunderstood in the exchange ?
