digitalmars.D - offsetof: Bug or Documentation Error?

reply "Garett Bass" <garettbass studiotekne.com> writes:
I found an inconsistency in the D Documentation.  In class.html, under the 
heading "Field Properties" there is an example:

class Foo
{
    int x;
}
...
void test(Foo foo)
{
    size_t o;

    o = Foo.x.offsetof;   // yields 8
    o = foo.x.offsetof;   // error, .offsetof an int type
}My own test code contradicts this, note that the error condition is 
opposite the example:class Foo {    int x;}int main() {    Foo foo = new 
Foo;    size_t o;    o = Foo.x.offsetof; // error: 'this' is only allowed in 
non-static                        //         member functions 
// error: this for x needs to be type Foo not                        // 
type int    o = foo.x.offsetof; // yields 8}

Starting to seem like a bug to me. The following code: class Foo { int x; } int main(char[][] args) { Foo foo = new Foo(); foo.x.offsetof; } gives a runtime assert error after main: Error: AssertError Failure test.d(11) -- Bruno Medeiros - CS/E student "Certain aspects of D are a pathway to many abilities some consider to be... unnatural."

Thats your main() not returning... A better error message would be appreciated. /Oskar

time (which incindently has a return from main) that I never noticed that. -- Bruno Medeiros - CS/E student "Certain aspects of D are a pathway to many abilities some consider to be... unnatural."
