CaptureGroup class

Capture a single, or a series of expressions and group them up as a single expression.

This allows a method of treating the expression like a reusable variable, by allowing a back-referencing, either by index or by name.

Example:

CaptureGroup(
  AlternationGroup(
    [
      RawExpression("gmail\\.com",),
      RawExpression("yahoo\\.com",),
    ],
  ),
);
// results in (gmail\.com|yahoo\.com)
