State of the Lambda

[Jesse Kuhnert]

Yes, saving characters is nice and all but what we really need are
better building blocks.

The community is holding it's breath, java7 means either continued
life / shelved language for better or more modern languages to run on
top of / or just something to abandon altogether.

I'm sure Oracle has it's own goals and needs, but some decisions live
on long after any one employer.

Are there numbers that show that inner classes with constructor arguments are common enough to make this extension of CICE worth the effort?  I suspect not.
