Defines a sequence parser where the parser used for each part depends on the previously parsed values.
p is applied to the (possibly empty) sequence of already parsed values to obtain the next parser to use.
The parsers obtained in this way are separated by sep, whose result is discarded and only the sequence
of values from the parsers returned by p is used for the result.
