[parenscript-devel] Problem with BLOCK and RETURN-FROM

(1) The following expression generates the correct code:

(defun blah () (λ () (foo 123)))

But it also emits "Warning: Returning from unknown block NILBLOCK", which is undeserved.

(2) It's not clear how to do explicit return from a lambda now. That is,

(defun blah () (λ () (when (foo) (return 123)) ;; do some other stuff ))

generates the same warning as above. Is this just a bug, or is it suggesting that one must explicitly declare a scope using (BLOCK NIL...) in order to do an explicit return warning-free? I'm hoping not the latter.
