Hello,

i try to learn the scope statements.

import std.stdio;

void main() {
{
scope(failure) writefln("5");
//writefln("Hallo");
}
}

The output from the program is 5. If i comment the writefln in, then it only 
print Hallo.
Is this the correct behavier?
I have thougt scope(failure) will only execute when the scope exit
abnormaly by throw. The 5 should never be occur by thi example.

It seems to trigger when the scope is empty, putting any other valid  
statement in the scope with the scope(failure) statement stops the output  
of "5". I suspect this is a bug.

Thank you

What might be happening (under 0.160) is that under some conditions DMD 
will insert an assert(0) at then end of a function to catch the 
no-return-statement bug. It's not supposed to do that with a void 
function but who knows.

I thought that at first, but there are 2 scopes involved. The main  
function and a 2nd scope inside it. The scope(failure) is inside the 2nd  
scope so should trigger if there is an exception in that scope, not if  
there is one in main. I added a return value to double check :)
