Add #'constantly, as specified by ANSI Common Lisp.
2010-02-22 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (constantly):
Add this function, from ANSI Common Lisp, using the SBCL extension
that extra arguments to it are passed back as multiple values in
the constructed function.
* cl-macs.el (constantly):
In the compiler macro for #'constantly, construct a
compiled-function object almost every time, at compile time when
all arguments are constant, and at runtime when they vary.
