All the D aficionados seem to wet their pants over meta-programming, but I struggle to find a place to use it.
IIRC, I used it in a couple of places when I was trying to write library stuff for MySQL, but in my current project, I use it only once. That's when I want to stuff something onto my undo stack. For that I have two template functions - push(T)(MybaseClass* p, T t, int ID), and pushC, which is just the same except that it checks the top of the stack to see if the ID there is the same as what it is wanting to push. This has served me very reliably, but I struggle to find other places in the whole application where I would benefit from templates. Is this typical - libraries use templates, applications don't, or am I just being unimaginative? Steve
