Expected distribution of lambda sizes (Re: Syntax poll, take 2)

[Neal Gafter]

Unfortunately, even with the Guava APIs and Java today, it is impossible to
write single-expression "lambdas" because anonymous inner classes require a
block for the body of the method.  Therefore it isn't clear how helpful your
statistics would be.
