Here's another one:
addTriple (s,p,o) = addArc s p o . addNode s . addNode p . addNode o
I like to think it's pretty straightforward.
I suppose you could argue that these are examples of "semi-point-free" style, or something. Certainly, I wouldn't want to rewrite tsArcFwd or addTriple into fully point-free style.
This is closest to where my code tends to end up. I like some of the implications of point-free style, but I generally tend to avoid point-free stuff involving functions which take more than one argument - in that case, I'll generally make at least one of the arguments explicit. It helps me write the function and makes the code more self-documenting - at least to my mind. Of course, point-free code becomes much clearer with a nice type signature. As does pretty much all other Haskell code.
