The old ones were:
- print/println
- printAny
- printf
- Console
The new printing story is just print/println. Every object can be printed.
You can customize the way it is printed by adopting Printable protocol. Full
details in comments inside stdlib/core/OutputStream.swift.
Printing is not completely finished yet. We still have ReplPrintable, which
should be removed, string interpolation still uses String constructors, and
printing objects that don't conform to Printable will result in printing
mangled names.

Because we're using a "brute-force" combination of conversion to
NSString and forwarding, this code will continue to work when String
is replaced by NewString. It may not be fast yet, but at least it
will flesh out the experience for Cocoa programmers
