I don't quite understand what fixed it but the infinite recursion is gone. 
That's visible both by usage and inspection, running ILDasm on 1.9 and current
shows that only in the older assembly does Versioned.CallByName call itself!

    D:\>ildasm.exe /text "\Program
Files\Mono-1.9\lib\mono\2.0\Microsoft.VisualBasic.dll"  | findstr "CallByName"
      .method public static object  CallByName(object Instance,
        IL_0004:  call       object
Microsoft.VisualBasic.CompilerServices.Versioned::CallByName(object,
      } // end of method Versioned::CallByName

    D:\>ildasm.exe /text
D:\cygwin\usr\src\mono\mono-basic\class\lib\vbnc\Microsoft.VisualBasic.dll  |
findstr "CallByName"
      .method public static object  CallByName(object Instance,
        IL_0004:  call       object
Microsoft.VisualBasic.Interaction::CallByName(object,
      } // end of method Versioned::CallByName

SVN doesn't show and changes to that code, so perhaps a compiler fix...


However I haven't managed to CallType.Get to work at all yet, I have been
successful with Set and Method.  The original case fails with
[[
