Are there some nice traits or internals to query the current call stack for address or perhaps even their (mangled) names. I'm mostly interested in using this to detect infinite recursions in my recursive descent parser. This provided that my parser slice hasn't changed since last call to the same function.

You can try to create an exception and get stack trace from it. The functionality is in druntime.

I've no idea how it is used but '_d_traceContext' might be of use:

import std.stdio;

int foo(int n)
{
	writefln("&foo: 0x%X", &foo);
	writefln("%s", _d_traceContext(&foo));

	return n;
}

extern(C) Throwable.TraceInfo _d_traceContext(void* ptr = null);

void main(string[] args)
{
	auto x = foo(100);
}

Found in object_.d in the druntime repo.

Ok, thanks. I just realized that http://code.dlang.org/packages/backtrace-d might be of use here aswell.
