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.

There's an easier way that does work in CTFE:

---------------------------

import std.conv;

enum x = 100;
pragma(msg, 1.text);
pragma(msg, "Hello " ~ 10.text ~ " world");
pragma(msg, "Hello " ~ x.text ~ " world");

enum y = 2.text;
pragma(msg, y);

//pragma(msg, 3.14159.text); // Ugh, ok, floats don't work though :(
