Abrupt completion during lookup of value of "groups" object.

14. For each result in results, do
[...]
j. Let namedCaptures be ? Get(result, "groups").
k. If functionalReplace is true, then
[...]
l. Else,
[...]
ii. Let replacement be ? GetSubstitution(matched, S, position, captures, namedCaptures, replaceValue).
Runtime Semantics: GetSubstitution ( matched, str, position, captures, namedCaptures, replacement )
[...]
11. Let result be the String value derived from replacement by copying code unit elements
from replacement to result while performing replacements as specified in Table 54.
These $ replacements are done left-to-right, and, once such a replacement is performed,
the new replacement text is not subject to further replacements.
12. Return result.
Table 54: Replacement Text Symbol Substitutions
$<
1. If namedCaptures is undefined, the replacement text is the String "$<".
2. Else,
a. Assert: Type(namedCaptures) is Object.
b. Scan until the next > U+003E (GREATER-THAN SIGN).
c. If none is found, the replacement text is the String "$<".
d. Else,
i. Let groupName be the enclosed substring.
ii. Let capture be ? Get(namedCaptures, groupName).
