Comment (by htebalaka):

 I was tempted to say precedence rules are the same on the type level.
 Prefix `Foo` should have higher precedence then any infix expression, and
 I ''thought'' that infix type operators took the same precedence as their
 value level versions, though when I tried to construct a quick example to
 illustrate in GHCi I didn't get that behaviour:
 {{{
 type family a + b
 type instance a + b = a
 type family a * b
 type instance a * b = b
 :kind! Int + Bool * Char
 Int + Bool * Char :: *
 = Char
 :kind! Int + (Bool * Char)
 Int + (Bool * Char) :: *
 = Int
 }}}
 :/
