The other reason to avoid excessive template instantiation is
that it inflates your compile time. A while back I changed my
custom assertf() and logf() functions to be non-templated in
exactly the way Jonathan M Davis described, and it shaved ~0.5s
off my 3s build time. This particular project is currently only
8000 LOC, but on a larger project you can see the hit could be
pretty significant.
