Small recommendation (apart from the reserved word issue which
you fixed): it's generally considered good D style to give
structs and classes names that start with capital letters,
JustLikeThis. So, I suggest Node rather than node.
Very minor point, and of course, your code is yours to style as
you wish, but it can be helpful to meet the "standard" style
conventions in order to make it as easy as possible for
everyone else to understand.
Thanks for the reminder. I use D Style when I am writing
properly, but haven't yet internalized it for a quick example and
old habits die hard.
