Inferred type is too general for high order operator with tuple parameter

[bugarela]

For some reason, the inferred type for optionSum is too general here:

quint/examples/cosmwasm/zero-to-hero/vote.qnt

Lines 492 to 501 in be9bb4f

	poll.options.listForall(option =>
	val optionKey = option._1
	// FIXME(#1167): Type annotation below is a workaround, inferred type is too general
	val optionSum: int = option._2
	// `ballots` only contains entries if there are > 0 votes.
	optionSum > 0 implies and {
	summed_ballots.keys().contains(optionKey),
	summed_ballots.get(optionKey) == optionSum
	}
	)

Symptoms:

• Bug in the type inference system involving nested sum types and tuples #1302

The quantification fix I'm working on will fix this issue 🎉
