Category theory text that defines composition backwards? I've always struggled with the convention that if $f:X \rightarrow Y$ and $g:Y \rightarrow Z$, then $g \circ f : X \rightarrow Z$. Constantly reflecting back and forth is inefficient. Does anyone know of a category theory text that defines composition the other way? So that $f \circ g$ means what we would normally mean by $g \circ f$.

I recall that the following textbooks on category theory have
compositions written from left to right.

Other examples appear in group theory and ring theory, e.g.

or several books by P.M. Cohn.
But in order to avoid confusion, authors usually do not use the symbol
$\circ$ for this. In particular when (as with noncommutative rings) it
is helpful to have both readings available (so that module homomorphisms
and scalars act on opposite sides). For instance, as far
as I remember, Lambek uses $\ast$ instead.
