comment LuaLaTeX does not work anymore since last MiKTeX 2.9 update (“fatal format file error”)
I have the same problem, and it's nothing to do with LuaTeX. It arose for me from following the instructions in tex.stackexchange.com/questions/67768/times-new-roman-font, but it also arises by going to MikTeX package manager and installing expl3 (although why it's required I can't imagine). MikTeX give the following information starting package maintenance... installation directory: C:\Users\jf3243\AppData\Roaming\MiKTeX\2.9 package repository: http://mirror.ox.ac.uk/sites/ctan.org/systems/win32/miktex/tm/packages/ lightweight database digest: b5c327843d7508f1caa13b621ac8f5cb

comment Test whether token list is empty
@Jan: We expect \ifx\a\b \ifempty{#1} \fi \fi to expand to nothing if the \ifx is false. But your definition does not have this property.

comment Test whether token list is empty
@TH: To solve this without assignment do something like \expandafter\helper\the#1 \sentinel\anothersentinel and then make \helper do whatever it takes, namely pick something out of the expanded #1. This probably means \helper has to expand to \expandafter\anotherhelper\string, and now it's getting complicated. And perhaps can't be reliably done, however clever we are with sentinel.
