Using ">" can be confused visually with "->", and I want to reduce those
chances.  I also prefer a style that is prefix oriented, and with constants
on the left.  I mentally combine the left constant and the infix operator
into a special case prefix operator.  This speeds my parsing because it
reduces stack depth and enables faster scanning.  This is particularly
helpful when the constant is narrow and the other operand is wider.
