It's useful in terminal, and in my opinion, it lets me write neater code too. I don't have to include lines like

if $$$ISERR(sc) { $$$ThrowStatus(sc) }

every time.

Yes, that's how it works.

If you don't want it to reset the sc, then you can leave out the R flag when you call the New() method. Just be aware that the error handling only triggers when sc goes from OK to an error, so it won't trigger again unless you manually set sc back to $$$OK.

@Evgeny Shvarov, I think I have submitted it to Open Exchange correctly. This is my first time using IPM, GitHub AND Open Exchange, so bear with me if I messed any of it up!
