> To preserve (future) transparency, yield is used instead of return.
I believe this is an abuse of the word "transparency." There's nothing
transparent about making the "return" keyword do double duty to mean "long
return." It's a new concept, and if and when it is to be supported in Java,
it deserves a new keyword.

This makes little sense to me. I don't think anyone would confuse a return
from within a lambda with a "naked return." People don't have that problem
with nested classes today.

When you say "future transparency," I believe that what you mean is
"allowing lambdas to be used to emulate control constructs in the future."
I think you should call it that.
