          Issue ID: 22152
           Summary: Block statement at beginning of statement not
                    recognized as function literal
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: Ajieskola gmail.com

```d
void main()
{ import std;
  {writeln("hello world");}();
}
```

Compilation attempt result:
```
app.d(3): Error: expression expected, not `)`
app.d(3): Error: found `;` when expecting `)`
app.d(4): Error: found `}` when expecting `;` following statement
app.d(5): Error: found `End of File` when expecting `}` following compound
statement
```

The compiler should recognize the block statement as a function literal that is
immediately called.

Note that it will compile with this change:

```d
void main()
{ import std;
  return {writeln("hello world");}();
}
```
