Re-thinking about it, I prefer having a format function returning a string, and
having a write function that doesn't apply formats:

write("this is ", 100, "% safe");
write("Used: ", format("%7.3f%%", num/max*100), ", free: ", format("%7.3f%%",
(max-num)/max*100));
write(format("Used: %7.3f%% free: %7.3f%%", num/max*100, (max-num)/max*100)));

Ciao

We have that format function in std.string; it just isn't documented.

But yes, an unformatted write function would be nice.  See my previous 
post on this thread.

DMD 0.95 bug: const struct is not const.
This code fails with "non-constant expression b" on the last line in DMD 
0.95.  It should compile normally.

    struct foo { int x; }
    const int a = 0;
    const foo b = { a };
    const foo c = b;

It's a sticky problem, but templating can't be done without it.

We now have a newsgroup dedicated to bug reports. I'm cross-posting to it.

FWIW, I've confirmed your bug.

To elaborate, members of const structs also fail.  (DMD 0.98)

----------
struct Qwert { int yuiop; }
struct Asdfg { int hjkl; }
struct Zxcvb { Asdfg nm; }

const int qaz = 15;
const Qwert wsx = { qaz };
const Asdfg edc = { wsx.yuiop };
const Zxcvb rfv = { edc };
int tgb = rfv.nm.hjkl;
