J is APL-inspired, and APL is right-associative, so that would surprise me. https://www.jsoftware.com/help/jforc/preliminaries.htm#_Toc191734304 https://www.jsoftware.com/help/jforc/preliminaries.htm#_Toc1... agrees with that, saying “All J verbs (functions and operators) have the same priority and associate right-to-left. For example, a b + c is equivalent to a * (b + c), not (a * b) + c.”* Your point about not needing operator precedence still stands, though.
