[IronPython] Overloads

The ref argument is, unfortunatelly, a bug. The conversion code tries to
convert int into int& which it fails to do. I'll get the fix out in the
next release.

Hi Martin,
Yes, I figured that out a little while later. Too bad I had already made
a fool of myself. ;-)

Surely there is not difference now and that is confusing.
Fair enough. Something else that struck me while I was fishing around
was that the doc string for both "ref" and "out" parameters show
"<typename>&" (where "<typename>" appears as the real type name).
Which, in turn, got me thinking about how one would go about specifying
an overload for methods that took ref/out params?
And finally, I'm having trouble calling functions with "ref" parameters:
>>> print Foo.__doc__
int Foo(System.Int32&)
>>> a = 5
>>> Foo(a)
IronPython.Objects.PythonValueError: Bad args for the method <method#
Foo on Sanity.Util.Helpers>
at input_5.Run(Frame frame)
Where "Foo" is defined as:
public static int Foo(ref int a) {
a *= 2;
return a * 2;
}
Other than that, the new overload selector stuff lets me dump a whole
bunch of my C# helper functions I had previously needed. Huzzah!
Keep the good stuff coming!
