If you try to use your data with chunkBy!"a != b+1", it does
not work, as expected.
What's the motivation behind this limitation?
Without it
chunkBy!"a + 1 == b"
is exactly what I want.
Probably it's an implementation problem. On source code you read:
// Issue 13595
version(none) // This requires support for non-equivalence
relations
@system unittest
{
import std.algorithm.comparison : equal;
auto r = [1, 2, 3, 4, 5, 6, 7, 8, 9].chunkBy!((x, y) =>
((x*y) % 3) == 0);
assert(r.equal!equal([
[1],
[2, 3, 4],
[5, 6, 7],
[8, 9]
]));
}
And other.
