Raw constructor for fact-infop structures.
Syntax:
(fact-info thm-name formula)
This is the lowest-level constructor for fact-infop structures. It simply conses together a structure with the specified fields.
Note: It's generally better to use macros like make-fact-info or change-fact-info instead. These macros lead to more readable and robust code, because you don't have to remember the order of the fields.
The fact-infop structures we create here are just constructed with ordinary cons. If you want to create honsed structures, see honsed-fact-info instead.
This is an ordinary constructor function introduced by std::defaggregate.
Function:
(defun fact-info (thm-name formula) (declare (xargs :guard (and (symbolp thm-name)))) (cons (cons 'thm-name thm-name) (cons (cons 'formula formula) nil)))
