I have the following code which does not work as I had hoped. I first
declare a function in a package...

BeginPackage["HSSV`cavity`"]
foo::usage = "now is the time..."
Begin["`Private`"]
bar;
nebbish;
foo[x_, y_] := 1 /; y === bar;
foo[x_, y_] := 2 /; y === nebbish;
End[]
EndPackage[]

And then try to run the following simple commands...

foo[1, bar]
foo[1, cavity`bar]
foo[1, HSSV`cavity`bar]

I had thought that the first one would have given me the correct answer,
as it works OK when I do not embed the function definition in a package.
The others were desperate second efforts that also failed. What am I
missing here?
