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.
