The other two that are surprising are the restrictions on "break" and
"continue" in the body of the lambda. The text is not very clear on whether
it is a restriction only on top level of the lambda (i.e. meaning strictly
that one can't use break/continue to leave its body), or on the entire body,
but as "break" and "continue" are listed alongside "return", and lambda body
is contrasted with method body, it would seem that the restriction is
universal. This seems to be very excessive - there's no ambiguity or
uncertainty when the loop to which break/continue belongs is itself
contained entirely within the body of the lambda, so why ban that?
