Cannot compile static properties for classes; static methods are fine

```
class Test {
static myTest = "abc";
}
```
fails to compile.

I'm getting around this by doing

```
class Test {
static get myTest() { return "abc" };
}
```
and `@language_out ES5` flag to get some kind of output.

Sadly, static property inheritance seems to really trip up the compiler. Before I relied on static values in my classes, I was able to get it to compile and work on the advanced setting - might even consider reverting my changes just to get it to work 100% again.

Any recommendations also welcome.
