This sample gives me ! Extra \else. l.6 \else and I don't see why. It is caused by line 5 and the sample is fine if I pull it out of the if or invert the logic, so the \setdefaultlanguage isn't followed by \else. Why is this happening?

   \PackageError{foo}{Cannot build with (pdf-)latex}{Use Xelatex or Lualatex}

  • with xelatex in texlive2013 I get no error and just reach the * prompt typing \stop exits cleanly – David Carlisle Sep 5 '13 at 20:56

    I too have no problem. It should be \expandafter\stop, anyway, so the conditional is properly terminated before the job ends in case the false branch is followed. – egreg Sep 5 '13 at 20:59
  • This is puzzling, I also use texlive 2013. Any idea where to start debugging this? – Max Sep 5 '13 at 21:00
