To put it in terms people here understand: suppose you have a big legacy code base written in C. It works fine but it's not perfect. And every time a bug comes up, there's a bunch of guys who say "hey, let's just rewrite the whole thing in Scala!"

No, we're not rewriting the whole code base on a production system just because you think Scala is neat. The existing code is fundamentally fine, let's focus on this problem today.
