Alas is does not because each does not accept additional
argument other than the range. Shouldn't be hard to fix
though.

You can thread multiple arguments through to `each` using
`std.range.zip`:
tenRandomNumbers
.zip(repeat(output))
.each!(unpack!((n, output) =>
output.appendln(n.to!string)));

Very interesting, thanks. It's a clever way to avoid the delegate
capture issue.
(Aside: A nested function that accesses 'output' from lexical
context has the same issue as delegates wrt to capturing the
variable.)
