I mentioned a similar (or perhaps the same?) issue in 
http://d.puremagic.com/issues/show_bug.cgi?id=588#c2. (The issue is 
marked as 'resolved' because this wasn't what it was directly about, it 
was about a patch to std.demangle; it just happened to run into an 
ambiguity concerning nested symbols)

It was probably just an oversight when nested symbols (and thus their 
mangling) was added to the compiler.

In my bugzilla comment I mentioned that adding a simple terminator 
character after identifiers would probably be the easiest fix. Since you 
have a fork of the frontend in descent, you could probably implement 
that pretty easily.
