const Swap([
  1. IdentifierableCollection first = const IdentifierableCollection(CitrusSyntaxList([LowercaseAlphabetS(), LowercaseAlphabetW(), LowercaseAlphabetA(), LowercaseAlphabetP()]))
])

Implementation

const Swap([
    this.first = const IdentifierableCollection(
        CitrusSyntaxList([
            LowercaseAlphabetS(),
            LowercaseAlphabetW(),
            LowercaseAlphabetA(),
            LowercaseAlphabetP(),
        ])
    )
]);
