A SeqParser is a parser for sequences. It wraps a function which takes a sequence and optionally returns a value successfully-parsed from the start of the sequence along with the rest of the sequence. If parsing fails it returns None.

You can construct a SeqParser using the seqParser computation expression. The bind operation of the computation expression will return the value parsed from the sequence and advance the sequence to the position where the next value can be parsed from. For example, given a parser parseValue, you can construct a parser which parses three values like this:

1: 
2: 
3: 
4: 
5: 
6: 

seqParser {
   let! value0 = parseValue()
   let! value1 = parseValue()
   let! value2 = parseValue()
   return (value0, value1, value2)
}

You can also call SeqParser.next and SeqParser.abort from within a seqParser to pop the next element of the sequence or to abort parsing respectively.

The function SeqParser.parseToCompletion takes a sequence and a SeqParser and will attempt to parse the sequence to completion.
