Captures groups of text according to a regex.

Every string coming through the text stream is passed through regex. is_captured tells for each group if something were found or not, captured contains the groups contents (or empty string if group is not captured). error is emitted only if regex contains error.

The regex syntax is Unicode-aware. Please refer to Regex Syntax in documentation for full syntax description.
