Interesting, I didn't see the [RFC](https://github.com/nim-lang/RFCs/issues/341) before. The `.?()` operator would indeed solve my problem.
By the way: I tried the workaround with the `()` operator, but I ran into the problem that I cannot differentiate between a function call `option.?foo()` or a field access `option.?foo`, and therefore do not know whether to return something that is callable with the `()` operator, or a simple field value.
