We have at times opted for an "easy to explain" rule rather than a semantically perfect one. For example, I've rejected several proposals to make function overloading more fine-grained on such grounds.
I've rarely met anyone who could explain how C++'s function overloading rules actually work, they just try arbitrary things until it selects the function they want it to.

Whats wrong with "If you think that, you have another thing coming."?
I've always understood it sort of like say your Father saying:
"If you think that [i.e. you can steal your little brother's ice cream cone], then you have another thing [i.e no ice cream, but maybe the leather strap] coming."

The first line:
int x2; // (at global scope)
The x2 resides in Thread Local Storage (TLS). A __gshared would put it in global scope. Still initialized to int.init which is zero.

D doesn't have global scope. C++ does not do TLS but that isn't relevant to the no cost position that C++ is taking.

It's an old saying, and in more modern English might be phrased "If you think that, you have another thought coming", i.e. you'll soon enough see why you're wrong.
