Force unfolding of (funcall #'(lambda () ...) if optimising, bytecomp.el. lisp/ChangeLog addition: 2011-10-03 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el (byte-compile-funcall): Sometimes the optimizer shirks its responsibility and doesn't unfold a lambda when it should. Do this here, if optimization is turned on; this makes inlining labels more consistent and trustworthy.
