Yeah, it worked, thank you. I knew it was something trivial like 
that. It appears I slightly misunderstood by this paragraph 
https://dlang.org/spec/arrays.html#array-copying - I missed that 
slice operator is supposed to be on the left-side rather than 
right (I thought adding `[]` to the `data` would do the trick).

Also, is this me and my bad English, or first comment in code in 
this paragraph (linked above, not in the discussion) is supposed 
to be something different? Shouldn't it be reference?
