I'd like to understand what the overhead is for this. How much overhead does this add when the remark is disabled? How much overhead does this add when the remark is enabled?

This is why I'm worried about overhead -- there can be *a lot* of array accesses in a complex TU and spitting data out to (potentially) stdout/stderr is *slow*.
