Or

          duck foo: 1 bar: 2

which is even more elegant, since it's the same syntax as Smalltalk <G>

Somehow I feel like I'm back in late 1981 or early 1982,  when Brad
Cox and Tom Love at ITT, I at IBM, and probably others, had read the
August 1981 issue of Byte magazine and were trying independently to
graft Smalltalk onto C independently.  Brad, Tom and I later became
friends when we met, but Objective-C certainly outlived ClassC which
never really got any visibility outside of Big Blue.

More seriously, I tend to lean on the side of making things like the
objective-c/ruby interface a little more visibility, since I've
learned that transparency isn't always what it's cracked up to be.
