n is "the index of the current value". Each time the lambda is called,

`a` is a tuple of the run-time arguments you pass to
`sequence`. In this example, no arguments are passed (empty
parens at the end of the call), so `a` is empty.

a[0] = 1
a[1] = 2

example,
Can someone give me a very watered-down explanation of what
std.range's recurrence! and sequence! do?
auto tri = sequence!((a,n) => n*(n+1)/2)();
