Yes, a read-only property...

There may be something that I don't know but I think assigning
to the .length property alone should be the same as reserving
and then assigning.

Newcomer to the D language here. I was going to use
`std.range.chunks` to get a two-dimensional, read-only view on
data in one continuous array.
But was surprised to find that this code doesn't compile:
import std.range : chunks;
import std.stdio : writeln;
void main()
{
int[] xs = new

It is, in this case. Reserve will extend the allocated length to n, but
not adjust the

opCmp is allowed to return float; so you could return float.nan in this
case.

Hello!
For example we can imagine struct Version.
Version can be old or new and can be 'badly formed' or
'undefined' or other 'not comparible' ('uncompatible') state.
Logically we can compare versions, but what must return `opCmp`
if one of versions has 'not comparible' state?
I think
