happy new year, @propensive!
Do you know why List#distinct is a `def` instead of a `lazy val` or `val` since `List` is immutable?
thanks!

As @dwijnand said, if it very a lazy val, every list would have an additional pointer. Given that each Cons points to just the tail, the additional pointer would double the size of every list... :(

Not sure where "very" came from in there...

Oh yeah, good point about it being an extra pointer on each Cons object.
