This is by design. The example works when modified as follows:
import std.stdio;
void main()
{
int i, j;
readf("%s", &i);
readf(" %s", &j);
}
The space before the second parameter tells readf to read and skip all
whitespace before attempting conversion.
I've implemented readf to be a fair amount more Nazi about whitespace than
scanf in an attempt to improve its precision. Scanf has been famously difficult
to use for complex input parsing and validation, and I attribute some of that
to its laissez-faire attitude toward whitespace. I'd be glad to relax some of
readf's insistence on precise whitespace handling if there's enough evidence
that that serves most of our users. I personally believe that the current
behavior (strict by default, easy to relax) is best.
