Re: [tlaplus] Proof by induction invoking the SequencesInductionTail theorem


I guess that these useful theorems need adapted versions to be used for recursive functions defined on multiple parameters (e.g. Sum[n, m \in Nat]
where recursion is done on one parameter having the other fixed) because key theorems/definitions like RecursiveFcnOfNat and 
NatInductiveDefConclusion are written assuming single parameter functions. I'm right?.

I recommend "currying" such functions, i.e. using functions of type [Nat -> [Nat -> S]] instead of [Nat \X Nat -> S] for TLAPS. Functions with several arguments are not or very badly supported at the moment (and this limitation has existed for far too long).
