D templates are analysed eagerly upon instantiation, whereas
C++ templates are analysed lazily. This is not a bug, it is a
feature.
Having browsed several hundreds bug reports lately, I've seen a
number of reports complaining that recursive templates
instantiation failed. I've resisted the urge to comment that they
were invalid. Although I do think they are invalid.
