I see nd-iota but it seems under powered(handling only the single 
argument case of iota)
I could spell that `auto fixediota(I)(I start,I 
end)=>iota(end-start).map!(a=>a+start)` to get the 2 argument 
version (3 arguments could be a little tricky)

soooo
```d
fixedndiota(???)=>...
ndfield(???)=>fixediota(???).map!(a=>foo.opIndex(a));
```

That doesnt seem premade anymore

Not about allocating, user defined opIndex on user defined data

If mir only defines a single data-type-family and is deeply 
opinionated about controlling it(which seems to be increasingly 
the case) its not generic and leaving some level of simplicity on 
the table.
