          Issue ID: 23680
           Summary: Support static classes in D
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: msnmancini at hotmail.com

D must support the following syntax:

```d
static class Abc
{
    void print(){writeln("Print");}
}
```

This should be expanded to:
```d

class Abc
{
    @disable this(); static:
    void print(){writeln("Print");}
}

```

Rationale:

(This *could* be a DIP, but I don't want it to get hidden from who's developing
the compiler, plus that's a trivial request and I don't want to lost time again
writing useless things)

1: Currently `static class` has no meaning and the compiler simply ignores,
which can surprise a lot of newcomers as it *seems* valid code but it doesn't
seem to work.

2: A lot of people comes from C# and Java to test D and they find it
inexcusable to not have them. D does not have a namespace keyword and that
behavior is not possible to simulate using a single file, so a class must be
used. This should be trivial to implement and would be a beginner friend
feature.

Keep in mind that every now and then it appears people trying to do that on the
D discord so this is overlooked all the time.
