No, that’s not an actual quotation. I was having a laugh at the silly logic which attempts to justify the benchmark. And preallocating isn’t a workaround, it’s idiomatic in Go.
And that’s a valid point for the set of applications whose purpose is generating garbage. But overwhelmingly this isn’t interesting and people mistake this benchmark for a useful indicator of programming language performance in the general case.
It’s not a very compelling defense of a benchmark to argue that it measures something different for some languages than others—in this case for Go the benchmark measures poorly/carelessly written code while for other languages it measures meticulously optimized code.
I maintain a contrived benchmark is not a useful benchmark.
Most people aren't building applications whose business requirements preclude preallocating memory except for languages which lack garbage collectors.
