           Summary: Unexpected compiler errors when using "as" keyword
           Product: Mono: Compilers
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#

Description of Problem:
Compiler gives error for certain expressions that use "as" keyword when the
VisualStudio compiler doesn't.

Steps to reproduce the problem:

Compile the following code.

using System;
namespace AsStringProblem
 class MainClass
  public static void Main(string[] args)
   object o = "Hello World";
   Console.WriteLine(o as string  + "blah");   // A. Error in Mono
   Console.WriteLine((o as string)  + "blah"); // B. Ok
   Console.WriteLine("blah" + o as string);    // C. Ok


Actual Results:
Line A produces a "error CS1002: Expecting `;'" error message

Expected Results:
The Visual Studio compiler doesn't complain about line A at all.

How often does this happen? 
Seems to happen when the "as" expression is followed by a +.
