*x = 1.234 for when T verifies is(T == int*) produces an error.

You can put an aditional argument in the function header:

void foo(T)(auto ref T t = T.init)
{
	static if (is(T == int))
	    auto x = new Thing!int;
	else static if (is(T == double))
	    auto x = new Thing!double;
	else
             static assert(false, "incorrect type");
	*x = t;
}
