使用 `raise' function 要求 `hy' 宏會在 `require' 上觸發 `raise'

Question

當試圖在另一個文件中require以下宏時， raise似乎會立即觸發：

(defmacro assert [a [b True] [message None]]
    `(unless (= ~a ~b) (raise (AssertionError (or ~message ~a)))))

這會導致AssertionError: True 。

重現步驟（有時有效，有時無效）：

echo '(defmacro assert [a [b True] [message None]] `(unless (= ~a ~b) (raise (AssertionError (or ~message ~a)))))' > a.hy
echo '(require a [assert])' > b.hy
echo '(assert True)' >> b.hy
hy b.hy

Answer 1

In another instance of Python evaluating function arguments before names, as stated by Kodiologist in their comment here and their answer on one of my previous questions "Non-existent hy macros runs assertions, but fails appropriately with everything else" , the issue was that unless當NameError不存在時並沒有觸發它，因為它在一年前從hy核心轉移到了hyrule 。
