You may think that 7 lines of nested if statements is the height 
of usability, **but NO**

```d
struct GooderResult(ErrorCause, DataType){
   ErrorCause error;
   DataType data; alias data this;
}
auto gooderresult(A,B)(A a,B b)=>GooderResult!(A,B)(a,b);
```
now users can just ignore the error entirely, without truthyness 
or an opinion on the subject, or inline handleing; and as we all 
know from the important thread of the philosophy of software 
design and walter, the best error is one that is defined to not 
exist

Therefore d style should evolve towards this:

```d
auto safedevide(int a,int 
b)=>gooderresult(b?"":"/0",b?a/b:int.max);
```

and for the rare cases you want to fail(why fail when you could 
just succeed? masochist)

```d
auto CRASH(T)(T t){
   assert(t.error,t.error.to!string);
   return t.data;
}
```

Or more realistically:
```d
auto replacefailure(T,S)(T t,S replace)=>t.error?t.data:replace;
```
