Discussion on: We don't need a ternary operator

An elision would cause its behavior to deviate from that of a ternary operator, though: if b is null/none then true ? b | 3 would return 3 whereas the ternary operation true ? b : 3 returns null.

That is the true strength of the ternary operator: to choose between two paths before evaluating them. All binary operators always have to evaluate one of their operands first.

That is true. And I think for that reason it'd make sense to raise an error if the true_value is an optional. It'd lead to a potential ambiguity in what is desired.
