Just glancing at your code, you've marked toString with @property, which is kind of a weird thing to do, nd if we ever make @property enforce that it's not called with parens, then that code won't work. So, you might try moving that @property: to after toString and see if that fixes your problem. But given the error, my guess is that the problem relates to the fact that you templatized the constructor, which is often problematic, and whatever type introspection std.conv.to is doing could be choking on that. So, you should probably try making it so that the constructor isn't templatized and see if that fixes the problem. - Jonathan M Davis
