EnumerateSequence

struct EnumerateSequence<Base : SequenceType>

The SequenceType returned by enumerate(). EnumerateSequence is a sequence of pairs (n, x), where ns are consecutive Ints starting at zero, and xs are the elements of a Base SequenceType:

var s = EnumerateSequence(["foo", "bar"])
Array(s) // [(0, "foo"), (1, "bar")]

Note:: idiomatic usage is to call enumerate instead of constructing an EnumerateSequence directly.
