Mangled symbols ending with Z?

[Peter Alexander]

DMD outputs quite a few symbols that end with a Z. For example:

module test;
class Foo {}

Gives me these three symbols (all .data)

00013680 D _D4test4Foo16__initZ
000136e0 D _D4test4Foo16__vtblZ
00013690 D _D4test4Foo17__ClassZ


I have two questions:

1. I know what __init and __vtbl are, but what is __Class?

2. What does the Z at the end mean? The D ABI page doesn't describe this 
in its grammar, and indeed std.demangle is unable to demangle these 
symbols. It expects a type there, and Z represents no type.


Once I know this, I will fix std.demangle so that it can parse these.
