This is part of the old dparse.d file:

private import std.string : ToString = toString ;

	char[] string()
	{
		static if(str)
		{
			static if(is(T == char[]))
				return t;
			else static if(is(ToString(t)))
				return ToString(t);
			else
				return "<<"~T.stringof~">>";
		}
		else
			return "<<"~T.stringof~">>";
	}

I have a problem with this part:  (is(ToString(t)) :
dparse.d(215): Error: function declaration without return type. (Note that constructors are always named 'this')

How to fix this code?

Pawel

I think (THINK!!) you could use __traits(compiles, ToString(t)) in place of the is(ToString(t)).

Unless all objects have an implicit toString? In which case it will always return true and be a useless check.
On the phone and couldn't check properly...

You must replace with

"static if (is(typeof(to!string(t))));"
