This package sometimes omits such error checking in the interest of
compactness and efficiency. For example, @code{cl-do} variable
specifiers are supposed to be lists of one, two, or three forms;
extra forms are ignored by this package rather than signaling a
syntax error. The @code{cl-endp} function is simply a synonym for
@code{null} in this package. Functions taking keyword arguments
will accept an odd number of arguments, treating the trailing
keyword as if it were followed by the value @code{nil}.
