| 10. Let stringElements be a new List. |
| 11. Let nextIndex be 0. |
| 12. Repeat |
| a. Let nextKey be ToString(nextIndex). |
| b. Let nextSeg be ToString(Get(raw, nextKey)). |
| c. ReturnIfAbrupt(nextSeg). |
| d. Append in order the code unit elements of nextSeg to the end of |
| stringElements. |
| e. If nextIndex + 1 = literalSegments, then |
| i. Return the String value whose code units are, in order, the elements in |
| the List stringElements. If stringElements has no elements, the empty |
| string is returned. |
| f. If nextIndex < numberOfSubstitutions, let next be substitutions[nextIndex]. |
| g. Else, let next be the empty String. |
| h. Let nextSub be ToString(next). |
| i. ReturnIfAbrupt(nextSub). |
| j. Append in order the code unit elements of nextSub to the end of stringElements. |
| k. Let nextIndex be nextIndex + 1. |
