Description bearophile_hugs 2011-02-16 16:21:58 UTC 
import std.stdio, std.bigint;
void main() {
    writefln("%10d", BigInt(10));
    writefln("%10d", 10);
}


It prints:
10
        10

Yes, that's a limitation of std.format. It only provides the character ('x', 'd', 's', etc). The same thing applies to std.complex.

If that's a limitation meant to stay, then writef is better to give a format error (possibly at compile-time!).

Of course it's not meant to stay.
