I pushed a very simple patch for this bug. It still isn't correct, because the resulting code generates a warning, but it's a lot closer to correct than not returning a return value at all. I wasn't sure how to make a correct fix, but I badly need this return value, and this can serve as an interim compromise. On a positive note, this shows how valuable the feature is! (Vladimir, when you get to this, feel free to undo my oversimplified change.)

I thought this was working at some point, but it doesn't seem to now. FOO() returns undefined in JS, when it should return 123:
(defun bar (fn) (funcall fn))
(defun foo () (bar (lambda () (return-from foo 123))))
It seems the value stored under the name "ps-return-value" isn't actually returned:
function foo() { try { return bar(function () { throw { 'ps-block-tag' : 'foo', 'ps-return-value' : 123 }; }); } catch (err) { if (err && 'foo' === err['ps-block-tag']) { err['ps-return-value']; } else { throw err; }; }; };
