.stringof is not the equivalent to .ToString(). .stringof is more of a 
compile time language feature. It turns an expression into a string:

import std.stdio;

void main ()
{
     string foo = "bar";
     writeln(foo.stringof);
     writeln((3 + 4).stringof);
}

The above code will print:

foo
3 + 4

The equivalent to .ToString() in D would be .toString() or 
to!(string)(variable).

There could be a couple of reasons for doing this. For example creating 
a DSL.
