No need to wait for the future, you can do this today:

	enum toStr(alias X) = X.stringof;

	enum x = 100;
	pragma(msg, toStr!1);
	pragma(msg, toStr!3.14159);
	pragma(msg, "Hello " ~ toStr!10 ~ " world");
	pragma(msg, "Hello " ~ toStr!x ~ " world");

Note, however, that this doesn't work in CTFE, only at template
expansion time.
