This is not a bug, as you have pointed out yourself you are using a binary plus and a unary plus operator in the same expression. This has been part of Python since version 1, and with operator overloading `obj + +thing` could mean whatever the objects want the two operators to mean. Unary plus is not necessarily a no-op. For example, the Decimal class gives a meaning to unary plus. `++` should never be an operator in the future, precisely because it already has a meaning today (either two unary pluses, or binary plus followed by unary plus). Even if the compiler could distinguish between the cases, the human reader would not. The first expression is not "unreadable". The fact that you were able to read it and diagnose it yourself as a binary operator followed by a unary operator proves that you can, in fact, read it. And it probably wasn't that hard to understand. (It wasn't for me.) It would be easier to read if you used spaces around the binary plus and no space between the unary plus and its operand, but it can still be read and understood even with the unusual spacing. ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39516> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
