他们是苹果和橙子，关于它们的性能问题实际上没有太多意义。
在大多数情况下，扩展实际上是一个静态函数，其性能与任何其他静态函数相同。
中缀函数只是提供了调用函数的另一种语法方式。中缀函数可以是常规成员函数或扩展。它们与它们的非中缀等效函数具有相同的性能。
英文:
They are apples and oranges and the question about their performance doesn't really make too much sense.
Extension in most cases is effectively a static function and its performance is the same as any other static function.
Infix function simply provides an alternative syntax for calling a function. Infix function could be both a regular member function or an extension. They have the same performance as their non-infix equivalents.
