By gmagoon:

also works for resonance form of benzyl with exocyclic double-bond, to my pleasant surprise:

benzyl-A
1 C 1 {2,S} {6,S}
2 C 0 {1,S} {3,S} {7,D}
3 C 0 {2,S} {4,D}
4 C 0 {3,D} {5,S}
5 C 0 {4,S} {6,D}
6 C 0 {5,D} {1,S}
7 C 0 {2,D}

Created new species: benzyl-A(1)
ChemFormula: C7H7J
1 C 0 {2,B} {6,B} {8,S}
2 C 0 {1,B} {3,B} {7,S}
3 C 0 {2,B} {4,B} {9,S}
4 C 0 {3,B} {5,B} {10,S}
5 C 0 {4,B} {6,B} {11,S}
6 C 0 {5,B} {1,B} {12,S}
7 C 1 {2,S} {13,S} {14,S}
8 H 0 {1,S}
9 H 0 {3,S}
10 H 0 {4,S}
11 H 0 {5,S}
12 H 0 {6,S}
13 H 0 {7,S}
14 H 0 {7,S}

The number of resonance isomers is 3
