2.x defaultIfEmpty for Maybe

[uzzu]

Hi. I'm glad that I started using 2.x and be able to use Maybe.
I started using it, and wanted to ask a question.

Now Maybe#defaultIfEmpty returns Maybe, but because this operator guarantees to emit data, I think should be Maybe#defaultIfEmpty returns Single.

I would like to know if there is a reason to return Maybe.

It was probably overlooked but we can't change the type now.

defaultIfEmptySingle that returns Single?

[akarnokd]

There is the toSingle(T defaultValue).

[akarnokd]

Also defaultIfEmpty is based on switchIfEmpty thus it returns Maybe.

OK. 👍
I write unit tests and it seems that there is no problem with substituting toSingle(T defaultValue), so I will use that.

[IMO] I think that defaultIfEmpty is more readable than toSingle , so I'd like to return Single in 3.x or future versions.

Thank you for answering my question 😄
