Is it possible to get the source expression sent to a lazy

So that I can implement something like

show(Arg)(lazy Arg arg)
{
    writeln(arg.sourceof, arg);
}

used as

    show(1+2+3);

will print

    1+2+3:6

No (afaik), what you need is an internal compiler function, 
"toChars" IIRC, that's available for each node.
