In C, you can use macros and functions in such a
way that enhances your productivity in implementing J.
The APL90 paper described the implementation of ,:
as follows:
Fl(laminl){R reshape(over(one,shape(w)),ravel(w));}
F2(lamin2){R over(a,reshape(over(one,shape(AR(w)?w:a))
,ravel(w)));}
I don't need the C++ features. My impression (could be
wrong) is that C++ compilers are more widely available.
