Oh... that looks more convenient than
```d
char[10] a;
a[0..5] = 'y';
```

Can't even initialize `a` with index `0` at point of declaration 
unless size of definition is same as size of array, basically 
making
```d
char[10] a = [0:'y',1:'y',2:'y',3:'y',4:'y'];
```
impossible.

Agh, maybe that thing needs to exist after all
