Hi,
I think I hit on a bug in GNU Emacs 24.0.94.1 (x86_64-unknown-linux-gnu,
GTK+ Version 2.24.10) of 2012-03-11. This cl loop is not parsed
correctly.
(loop for rms in nil
when t
do (loop for (gnu . emacs) in nil)
end)
Backtrace when evaling this form:
backtrace
Description: Text document
(loop for (gnu . emacs) in nil)
is parsed and executed correctly, so is
(loop for rms in nil
do (loop for (gnu . emacs) in nil))

Thanks, installed.
