Returning rules ...

Hi,

We are familiar with functions such as Solve[] that return results as a
series of rules.  My question is how to define a Module that does
essentially the same thing.  For example, I'd like to be able to do 
	test = MyFunction[args];

where MyFunction[args_] := Module[
	{},
	...
	Return[{...}];
	];,

and have test returned as the list
	test = {
		Value1 -> val1,
		Value2 -> val2, ...}

Can anyone suggest a straightforward means of accomplishing this without
resorting to Global` variables?  Sample code (eg
Statistics`LinearRegression` that returns results in the form I've
described above) has not proved particularly helpful.

Many thanks,

Dave.
