Performance implications of the lambda draft specification

[Joshua Bloch]

John,

I've learned the hard way that this line of reasoning can lead to pain.
 When I designed the collections framework, I was assured that the cost of
creating and using an iterator to traverse an ArrayList would vanish due to
VM-wonderfulness.  That was 13 years ago.  I'm still waiting.
