Given how complicated the StringInterpolationConvertible protocol is, I'm not
sure it's a good idea to invoke all of that machinery merely to convert an
expression to a string. I mean, you end up with code like:
String(stringInterpolation:
String(stringInterpolationSegment: ""),
String(stringInterpolationSegment: expression),
String(stringInterpolationSegment: "")
)
That seems like a lot of code to generate for such a simple task.
(And you can have those empty segments over my dead body—they're very important
to a lot of interpolation use cases, because they allow you to distinguish
between the literal and interpolated segments. If you want to design a
different mechanism that's more efficient and equally capable, well, I'm happy
to talk about improving StringInterpolationConvertible any time you are, but
it'll definitely be opening a can of worms.)
