Counting the brackets would work in the given example, but not with others. Example: { { 1 } { 2 } { 3 } { 4 } { 5 } { 6 } { 7 } }, which I believe should have a nested depth of only 2. So there's a need to track the current depth as the opening and closing brackets are encountered when parsing.

Then there's situations like { "{{{}}{{" }. While it's probably overkill for the specific need here, it's the type of thing that I think about when coding System RPL. Unanticipated input in that environment can have serious consequences.
