I don't think I know the size of the arguments.

If I pass in "123" and MySpecialType('a'), the result should be:

assert(foo("123", MySpecialType('a')) == [MySpecialType('1'), MySpecialType('2'), MySpecialType('3'), MySpecialType('a')]);

What should the length of the pre-allocated array be?

In my try, I iterate the args twice. The first time to calculate the number of elements, then preallocate and then iterate them again and constructing the proper objects.

It is not nice, but about 1/3 of time, compared to original version, compiled in release mode.

Yeah, I will probably need to iterate twice.

Thanks a bunch 👍
