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.
