Hello everyone,
in java, you can have exceptions on methods.
Thus we can write:
public static void control (String string) throws
MyException {}
Is that possible in D and if so how does it work? If I write this
D:
public void testMe () throws MyException {}
The compiler refuses to compile.

What is the proper behavior for this D?
D doesn't have that Java syntax, because it was widely regarded
as a Java design mistake. So in D omit the throws part. If your
function tree doesn't throw exceptions (but it can throw errors)
add a nothrow.

Just a general FYI:
Classes are relatively heavyweight in D.
By the way the weblink is:

How many of these? In order to justify saving 8 bytes per

I don't doubt your reasons, but then again, you have what you
have right now in D. Asking for more, you have to provide it,
