常见的想当然

When allowTrailingOptions is false, option-like arguments after the first positional argument still trigger validation, and the double-dash separator is consumed as a special token.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• Disabling allowTrailingOptions causes option-like arguments and the double-dash separator after a positional argument to be treated as literal positional arguments in results.rest rather than being parsed or consumed.
• assert parser with allowTrailingOptions: false treats --mode and --verbose after a positional argument as literal positional arguments in rest rather than parsing them
• assert parser with allowTrailingOptions: false preserves the double-dash separator in rest rather than consuming it
• assert default parser with allowTrailingOptions: true consumes the double-dash separator and parses options normally
