then<R7> method
Returns a parser that consumes the receiver followed by other in
sequence and returns a SequenceParser7 with the 7 positional
parse results.
Flattens into a strictly typed Record with 7 elements, preserving static type information.
For example,
the parser char('a').then(char('b')).then(char('c')).then(char('d')).then(char('e')).then(char('f')).then(char('g'))
returns ('a', 'b', 'c', 'd', 'e', 'f', 'g')
for the input 'abcdefg'.
