I assumed that most know that X->m is just shorthand for (*X).m, 
presumably created or adapted because the alternative (thanks to C's 
prefix dererence op) is so ungainly.

But X->m and (*X).m both do member selection; they are conceptually the 
same thing.

I kept X[i] and *X separate because they are conceptually different. (I 
expect if I'd had only *X, you would have complained that X[i] was missing.)

Note that the decription I added in the comment says only 'member 
select'. What would your descriptions have been for X.m and X->m?
