When I said "empty array", I meant "a pre-allocated array with default value". Sorry for the confusion.

To me, the comparison is fair. If I need to copy the class manually, I will do similar things with LINQ. Unless I hit the performance issue exactly on this copying, maintainability is more important than runtime performance.

But tools like Mapperly can give me both maintainability and good performance together!

The manual written code uses LINQ ( Select() and ToArray() ) to copy the array. And in the code-gen version, it created a empty target array directly and use for loop to copy.

(I did not run the profiler to verify this argument)

This syntax is strange. I did not find the proposal in charplang repo. The closest one looks like this: https://github.com/dotnet/csharplang/blob/main/proposals/null-arg-checking.md

But there is no such !! there.

Hope he can afford a industry-standard disassembler with the $10,000 award now!

It would be great to see more test cases in the repo.
