我得到了错误:
Ambiguous call resolved as CORE::join(), qualify as such or use & at
当我将错误修复为:
$args = CORE::join( ', ', @$args );
一切正常。
但是当我将其修复为:
$args = &join( ', ', @$args );
正如错误消息所建议的,我得到了不同的错误:
Can't locate object method "_make_instance" via package ", " (perhaps you forgot to load ", "?) at
为什么第二次修复不起作用?
