Hi,

When uncommenting mixin(prog);
It gives
```

Hi realhet,
I can explain what happens here.
When you write `auto x = mixin(bla);`
The mixin it parsed as an expression.
b/c there can only be an expression after the =.
However when you don't do that the mixin is parsed as a
statement, after which a ; is expected and mandatory.
putting a ; into the string generated by prog should fix that.
