You could change that to : assert(t != NULL)

I think the VTK community would okay assert's. They compile only when
_DEBUG is defined; ie no overhead in the release version. That said,
Berk is right, that in this case it doesn't provide very useful
information..

Mimicking some of boost's compile time and static assertion's might be
good for VTK, to enable bounds checking and traits validity even in
performance critical code.
