Classes type promises currently provide several attribtues that take a list of classes to use as input.

Classes type promises do provide for not but it is singular.
> $ cf-promises --syntax-description json | jq '.promiseTypes.classes.attributes[] | select(.type=="context") | .attribute' "expression" "not"
It would be nice to be able to define a class based on a list of classes, expressions, or functions that evaluate to false like the opposite of and.
For example:
bundle agent __main__
{
classes:
"all_true" and => { returnszero("/bin/true", noshell), "cfengine", "cfengine.cfengine_3" };
@if feature(CFE_3458)
"none_true" none => { returnszero("/bin/false", noshell), "Not_Defined", "cfengine.Not_Defined" };
@endif
reports:
"all_true defined" if => "all_true";
"none_true defined" if => "none_true";
}
R: all_true defined
