           Summary: [optimization]: std.conv.parse!(int, string) counts
                    when doCount is false
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos
          Assignee: nobody@puremagic.com
          Reporter: jack@jackstouffer.com

Counting increment instructions are still issued in std.conv.parse!(int, string) when the doCount template parameter is false. These lines should be behind a static if and save a couple of cycles.
