.. remove quotes from strings made up solely of a lone scalar (..), as the interpolation of such serves no purpose.

Good catch; I'd go even further with that advice and say you should never do it unless you know why not. It can potentially be very harmful since it stringifies anything: references are flattened into useless text. That's very unlikely to be something you are intending. In the case of other kinds of scalar values, it's no harm, however neither does it do anything useful.

So while it doesn't necessarily hurt, it doesn't gain you anything either. And occasionally it can hurt big time. Bottom line, don't do it.

Makeshifts last the longest.
