Re: [swift-users] Implicitly capture a mutating self

[Zhao Xin via swift-users]

I did not test the code. But if you cannot implicitly capture a mutating
self, you should do it explicitly, right?

let blockSize = min(512, count)
let blockCount = (count+blockSize-1)/blockSize
device.sync { *[self] () -> () in* // Launch CUDA kernel
    try! fill<<<(blockSize, blockCount)>>>[
        .pointer(to: &self), .value(value), .value(Int64(count))
    ]
}

Hope above code works.
