Agreed, and writef is even better:
writef("x is %d",vx," y is %g\n",vy);

No need to put the format string on one side and variables on the other 
side..

It has still deficiencies:
- a syntax 'a la Ruby' would permit to see better the resulting string:
writef("x is %{vx}, y is %{vy}\n"); of course you could still specify 
the format if you want: writef("x is %08x{vx}\n");

- why writef doesn't call to_String on struct or on a type?
I.e:
typedef int foo;

char[] toString(foo x)
{
	return "foo";
}

doesn't work as expected in a writef, same with a struct defining a 
toString function..
