Silence unused returned value warning

No description provided.

In other places we use:

#include <utility>

//...

std::ignore = //... stuff that returns value you want to ignore

which is more descriptive than the (void) idiom. Maybe let's be consistent with that?

@copilot Can you try doing the changes I requested in a comment?

[Copilot]

@MiKom I've opened a new pull request, #107, to work on those changes. Once the pull request is ready, I'll request review from you.

Bleh, copilot went off rails and did a different thing :)
