That explains it. I kind of wish I'd known that a few hours ago :)
It would be nice if DMD would issue a warning when redefining a 
non-virtual function in a subclass. I might have to start using 
"override" more often despite force of habit and dislike of its 
verboseness. Perhaps "override" should be implied by default 
since it's by far the most common case. In cases where the 
programmer really wants to redefine the function non-virtually, 
there could be a keyword that would handle that. It could reduce 
extra typing and save beginners hours of stress :)
