[swift-evolution] Add conversion String -> Bool

[David Sweeris]

You may be right, but I'd imagine such a conversion function would be in pretty much any library for serializing/deserializing data.

I can't recall if this has been discussed before, but are we committed to One Standard Library to Rule Them All, or might we consider having a "standard" library and a "common extensions" library? (Personally, I'd prefer them to be split up so that 3rd-party library authors can import only what they need, but maybe that's just me.)
