@code{defun} defines a symbol as a function, creating a lambda
expression and storing it in the function cell of the symbol. This
lambda expression thus becomes the function definition of the symbol.

@end defun
@defun plist-member plist property
-@tindex plist-member
This returns non-@code{nil} if @var{plist} contains the given
@var{property}. Unlike @code{plist-get}, this allows you to distinguish
between a missing property and a property with the value @code{nil}.
