  RegExp.prototype [ @@replace ] ( string, replaceValue )

  [...]
  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).
