Actually, that's not the reason why Common Lisp accepts that.  The 
reason is that the loop macro only looks at symbol names.  In Common Lisp

(symbol-name :a) => "A"
(symbol-package :a) => #<PACKAGE "KEYWORD">
(symbol-name foo:a) => "A"
(symbol-package foo:a) => #<PACKAGE "FOO">

while in Emacs

(symbol-name :a) => ":a"

Wouldn't it be nice if Emacs finally decided to have Common Lisp packages?
