__typename always returned in type even if field not present in query

[lmatteis]

Does anyone know why __typename gets returned in my result type, even though it's not explicitly selected for in the query? I'm sure there's a reason for this but can't figure out why.

There's one where case where we now explicitly add it as an optinal property like in your example. It's basically in interface/union cases, to prevent types not correctly collapsing when a __typename field hasn't been selected explicitly.

More info here: #102

It's marked as optional though to prevent you from accidentally assuming it'll actually be present.

Thanks makes sense
