Operators default to infixl 9 unless specified otherwise, so no infix declaration is needed.
Why there is a default infix? Why it is 9?
That's what the Haskell Report says: "Any operator lacking a fixity
declaration is assumed to be infixl 9" (section 4.4.2).
Any function with at least two arguments can be used as an operator,
so there has to be a default. Presumably, infixl 9 was considered the
least surprising.
