Proof step 2 from proof validstatfields-validstatfield-01 (previous step)

initdone(class, st), tdname∃(str, class), sk ∈ statfields(class), ∀ class, sk. tdname∃(str, class) ∧ initdone(class, st) ∧ sk ∈ statfields(class) → validstatfield(str, sk, st) ⊦ validstatfield(str, sk, st)

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument
