>From https://issues.dlang.org/show_bug.cgi?id=9816#c19 :

There are some problems with the current implementation.

export void foo() {} // definition  => dllexport
export void foo();   // declaration => dllimport
export int a = 0;    // definition  => dllexport
export int a;        // declaration => dllimport // fails because it's actually
a definition
export extern int a; // declaration => dllimport
