Nobody understands templates?

[Steve Teale]

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?
