--- Comment #13 from Jakub Łabaj <uaaabbj...@gmail.com> --- I understand now, thanks! You can find my profile here: https://github.com/byebye. I've create a simple PR: https://github.com/dlang/phobos/pull/5040 for similar issue involving formattedRead, where I was wondering if I should restrict arguments to pointers. So it seems the solution would be exactly the same in both cases. --
