Every permutation of [S,V,O] appears in 'nature':

I disagree, it's easier with postfix functions. With prefix functions,
to get line-up you insert space in the middle of the line. With
postfix notation you would often insert space at the beginning of a
line, a much easier place to insert text, because there is a
keystroke, in most text editors, to take you to the beginning of a

Postfix, of course! So you'd write
data a Tree = Leaf | a a Tree
Confusingly, ocaml does something like this, with postfix notation for
types and prefix notation for function application.
