<div dir="auto">I don't know the historical answer, but I think it's because the true fixity can't be expressed in Haskell. As far as I can tell, there's no operator with the same precedence as && or || that can be meaningfully combined with it. But if these operators were defined just "infix", then we'd have to write junk like x || (y || z). So instead we picked a direction out of a bag and never had a reason to look back.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Apr 11, 2019, 10:13 PM Richard Eisenberg <<a href="mailto:rae@richarde.dev" target="_blank" rel="noreferrer">rae@richarde.dev</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi café,<br>

Why are && and || in the Prelude right-associative? This contradicts my expectation and the way these work in other languages. That said, I can't think of any harm in it. This came up from a question asked by a student, and I have no idea why the design is this way.<br>
