Non-throwing dematerialize for result using NoError

[ileitch]

I'm pretty new to using Result, so perhaps this is possible by another concise means.

A variant of dematerialize that doesn't throw if the error type is NoError would be nice to have. I typically avoid try! throughout my code, and use SwiftLint to warn against its use. My options here are to use a magic comment to disable the SwiftLint rule, or do/catch - neither is particularly appealing. Thoughts?

The question is how that would affect type inference. I think it'd be fine to include if it doesn't introduce ambiguities. 👍
