[Insight-developers] itkSuperclassTraitMacro

[Cory Quammen]

I didn't know about that macro either, but it actually looks useful. I
really hate having to write, e.g.

typedef typename Superclass::PixelType PixelType

over and over, or even having to copy and paste it.

This

itkSuperclassTraitMacro(PixelType)

looks a lot nicer to me, but I suppose it makes code that much more opaque.
