import std.range;
import std.stdio;

void main ()
{
    auto range = sequence!((a, n) => n);

    // works, but the chunks are all the same length
    auto rngs = range.chunks(4);
    writeln(rngs[0]);
    writeln(rngs[1]);
    writeln(rngs[2]);

    // want this
    auto ranges = range.???(3, 4, 5);
    writeln(ranges[0] == [1, 2, 3]);
    writeln(ranges[1] == [4, 5, 6, 7]);
    writeln(ranges[2] == [8, 9, 10, 11, 12]);
}

Do you know of a simple way to do this? It's essentially similar to chunks, except the chunks themselves would not be of the same length.

You can think of a good name for '???' here. Maybe this is already possible by combining functionality in std.range - but I came up short.

You likely want to get involved / raise your support here:
