I dunno about that... AlamoFire and SwiftyJSON both use it, and are quite
popular with rank-and-file Swift programmers.  It's certainly not popular
in the Objective-C community (where the syntax doesn't really support it),
but it seems like the Swift community may be warming up to it.

I also like the idea of a dedicated method-cascading operator, like what
Dart has.  It eliminates the need for a programmer to explicitly remember
to 'return self' at the end of a chainable method.  Not sure how well it'd
integrate with SE-0047 (@discardableResult) though.
