I doubt. However, you can use platform-specific popen() (POSIX) and _popen()
(Windows) for that. I recently talked about this on IRC. At the moment

I saw that a few minutes after posting as well, but if the only time
it's going to actually check the definition is if I instantiate it,

I can see the case for a grand-child, but if a class does not provide

association, abstract?
Classes become abstract if they are defined within an abstract
attribute, or if any of the virtual member functions within it are
declared as
Because the function in this case has no definition in the base
abstract class (Parent), but is referenced / called by Parent's
members. I did not want Parent to provide a default definition for the
function precisely because a large point of the abstract was that
method.

Hello again!
A third question on D:
Is there an argument type I can provide for a method signature
which would require a user to provide classinfo or a class name for
a class of a particular type?
That is, suppose I have a Class called Fruit.
Is there some constraint I can impose, either in the
Nevermind - sorry for the clutter.
For those who are apparently as dense as I am, this can be roughly
accomplished via Template specialization:
class Fruit {}
class Apple : Fruit {}
class Celery {}
void mustBeFruit(T : Fruit)() {
writeln(T.classinfo.name);
}
void main() {
.classinfo is for getting information about an object at __runtime__.
For the example given here, you don't even need templates:
void mustBeFruit(Fruit fruit)
{
writeln(fruit.classinfo.name);
}
Since Apple, Banana, and Orange inherit from Fruit, they __are__ Fruit and
can be passed to

Ah; I should have clarified - I didn't want an *instance* of the

provide class info specific to a type of class.

If that code is legal, then in my opinion it's the rules of the language that

Some C(++) compilers understand printf and will warn if the format string
doesn't match the arguments, but even this is rare AIUI.
