          Issue ID: 13055
           Summary: @nogc std.string.sformat
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: Phobos
          Assignee: nobody at puremagic.com
          Reporter: bearophile_hugs at eml.cc

sformat uses the given buffer, so this should compile:


void main() @nogc {
    import std.string: sformat;
    char[50] arr;
    sformat(arr, "%d", 100);
}


If the given buffer is not large enough, sformat throws an exception. I think
throwing this exception should not require a GC memory allocation at run-time.
