When using this hack, I prefer `fromInteger x = repeat (fromInteger x)`.
That way, you get
> 2 * [1,2,3]
[2,4,6]
It's cute for playing around, but the Num instance for lists is somewhat
discouraged in "real" code.

I guess you meant
(*) = zipWith (*) ?
Dumb question: would it be fine to use such an instance in real world application code (in contrast with library code... I guess it would be frowned upon there?)
are there any "dangers"... weird interactions?
