Keywords improvements

Keywords in expression statements

void Test(Action action)
{
    action();
}
static void Main(){
    Test(() =>
        // invalid expression term 'unsafe'
        // ) expected
        // ; expected
        unsafe {
            Console.WriteLine("unsafe");
        }
    );
}

Multiple keywords usage

static void Main(){
   unsafe fixed (byte* p = new byte[] { 1, 2, 3 })
   {
        Console.WriteLine("fixed pointer");
   }
}

for loop example

static void Main(){
   unsafe fixed (byte* p = new byte[] { 1, 2, 3 }) for (int i = 0; i<3; i++)
   {
        Console.WriteLine(p[i]);
   }
}

These scenarios are totally different restrictions.

Keywords in expression statements

This is in fact block for expression-bodied lambda.

Multiple keywords usage

This is allowing unsafe block omitting braces.

for loop example

This too. fixed and for can be embedded in this way now.

   unsafe 
   {
       fixed (byte* p = new byte[] { 1, 2, 3 })
       {
            for (int i = 0; i<3; i++) {
                 Console.WriteLine(p[i]);
            }
       }
   }

?

[huoyaoyuan]

using System;
public class C {
    static unsafe void Main()
    {
        fixed (byte* p = new byte[] { 1, 2, 3 }) for (int i = 0; i<3; i++)
        {
            Console.WriteLine(p[i]);
        }
    }
}

This is already valid. I mean fixed already has this ability.

i have no words, you won

"Keywords in expression statements" idea came to me from that:

just one less bracket
