Hello fellow printfers!
While I'm just as ashamed of my printf habits as the next guy, I think it'd
be great if we could move forward with this somehow.
Coming from a background in Qt, the stream operator syntax looks perfectly
normal to me, perhaps you could expand on why we want to avoid using these
in WebKit. Is there a technical reason, or is it more of a language purity
Regardless, adding a consistent set of debug(WebCore::MyCoolOverload)
methods as suggested would still be massively useful.
