I'm trying to use mixins and enums to "expand" code in place 
but the results are not what I expected and I'm getting an 
weird error. I have created the smallest possible example to 
reproduce the error and it is the following:

[...]

Try this:
```d
pragma(msg, type_check!("static if", "i8", "true", "5", "4", 
"10", "5"));
```

Result:

```d
static if(is_same!(num, i8)) {
    mixin(base_digit!("5", "4", "10", "5"));
    static if (true) {
      mixin(overflow_check!"i8.min"); }
  }
```
is_same - is undefined
i8 - is undefined
overflow_check!"i8.min" - ?


This code with mixins is horrible :)
