Yes, I know. Of course your proposal is totally consistent in its own right.
I just found the approach a bit 'hybrid': it surrounds the expression
deonoting the lambda's types within angular brackets, but then
introduces a different style for this expression, using round brackets
for the arguments.
Note that with your proposal the signature for a 'Runnable-like' lambda becomes:

lambda<void()> runnable = new lambda<void()> {
System.out.println("Hello world!"); };

which, to my eyes, looks arguably less elegant than the equivalent
with my proposal:

lambda<void> runnable = new lambda<void> { System.out.println("Hello
world!"); };

Simply because the first type variable denotes the return type 'void',
having no need for the empty parentheses.
