I too remember that once I needed a ternary operator. But at that time, I
was new to blitz and could not do it.
However, I just have been able to write ternary support classes for blitz.
The sample code is attached.
However, this code is written with assumption that your compiler supports
templates arguments in template parameters.
Look for
#define BZ_TEMPLATES_AS_TEMPLATE_ARGUMENTS
in blitz/config.h
If it is defined, it should work.
Also, since I have just written it, so I am not able to test it quite
well. Just let me know if there are any problems.

applyStencil takes upto 11 arguments. Why donot you pass your individual
arrays to applyStencil and evalulate the expression
in stencil code?

PS: Julian, may be you add this code to blitz? The code is pretty straight
forward. Just extended Binary Expression classes for ternary operators.
