pub fn complete(&self) -> &str {
        self.get(0).expect("match has no complete text")
    }
Gets the complete text of a match.

All [`Program`]s have an implicit capture of the complete text at index
zero. This function is therefore equivalent to unwrapping the output
of the [`get`] function with index zero.

[`get`]: crate::MatchedText::get
[`Program`]: crate::Program
