http://dlang.org/phobos/std_stdio.html#.File.ByLine Description is "Range that reads one line at a time. ditto". The "ditto" should not be there.
Already fixed in master. https://github.com/D-Programming-Language/phobos/commit/4c713c311ddb7601aad3b04430f38c26dd256119#std/stdio.d Just hasn't made it onto the live site yet.
Marking as previously fixed.
This bug seems to have recurred: http://dlang.org/phobos/std_regex.html#.replaceAllInto The second overload of replaceAllInto isn't being recognized as an overload; it's placed in its own entry with "ditto" as the body.
Maybe this is a bug in ddox.
It's gone in master, might have been a dmd issue. http://dlang.org/phobos-prerelease/std_regex.html#.replaceAllInto Maybe related to this fix. https://github.com/D-Programming-Language/dmd/pull/4639
Verified it's now gone. Weird. Probably a transient regression that got fixed shortly afterwards?
