currently it works kind of ok. but what it's missing is check on 
what none of [static if]s have worked. Ideally, I would want an 
static 'switch here', so I could make `static assert(false)` in 
it. and/or I'd like some sort of [compile time variable] to 
change it if  [static if]s have worked and check such [compile 
time variable] later.

I mean something like
```D
static switch (v.mode)
{
default:
    static assert(false, "v.mode" is invalid)
case "gs_w_d":
  // etc...
}
```
