---------------------------------------------------------------------- UNWIND_ALL_BUT_RIGHT_RULE (unwindLib) ---------------------------------------------------------------------- UNWIND_ALL_BUT_RIGHT_RULE : (string list -> thm -> thm) SYNOPSIS Unwinds all lines of a device (except those in the argument list) as much as possible. LIBRARY unwind DESCRIBE {UNWIND_ALL_BUT_RIGHT_RULE l} behaves as follows: A |- !z1 ... zr. t = (?l1 ... lp. t1 /\ ... /\ eqn1 /\ ... /\ eqnm /\ ... /\ tn) --------------------------------------------------------------------- A |- !z1 ... zr. t = (?l1 ... lp. t1' /\ ... /\ eqn1 /\ ... /\ eqnm /\ ... /\ tn') where {ti'} (for {1 <= i <= n}) is {ti} rewritten with the equations {eqni} ({1 <= i <= m}). These equations are those conjuncts with line name not in {l} (and which are equations). FAILURE Fails if the argument theorem is not of the required form, though either or both of {p} and {r} may be zero. May loop indefinitely. EXAMPLE #UNWIND_ALL_BUT_RIGHT_RULE [`l2`] # (ASSUME # "!f.
