--- Comment #3 from berni44 <bugzilla at d-ecke.de> ---
I filed two more issues: Issue 20392 and Issue 20393 to distinguish between the
different problems.

Here the problem is, that this works, but the one above not.

---
import std.format;

void main()
{
    string str = "foo bar buzz";
    string a, b, c;
    formattedRead(str, "%s %s %s", &a, &b, &c);
}

IMHO %*s should be added (and several others like %*x) to fix this bug.

As atilaneves and MoonlightSentinel pointed out in PR 7277, the error is
correct, because this is high likely a programmers error and not a user
mistake.
