DAML FP intro is mentioning the concept of fixity and is referring to the Haskell report for more details. That’s all good.
However, the DAML documentation does not mention the fixity of operators. In contrast, the Haskell documentation does, which I think it should, because the fixity of an operator affects is semantics, I would argue.
Is this something that can be added? Until then the workaround is to use the Haskell documentation under the assumption that the DAML implementation has chosen the same fixity for common operators.
