// Interface for the class Sequence. A sequence contains a single set
// of variables, all at the same lexical level just like a structure
// (and like a structure, it may contain other ctor types...). Unlike
// a structure, a sequence defines a pattern that is repeated N times
// for a sequence of N elements. Thus, Sequence { String name; Int32
// age; } person; means a sequence of N persons where each contain a
// name and age. The sequence can be arbitrarily long (i.e., you don't
// know N by looking at the sequence declaration.
