expl3: don't understand behavior of tl_if_novalue:nTF

Postby erwann » Sun May 06, 2018 2:13 am

Before opening a ticket bug I'd like to make sure it is one indeed.
  1. \documentclass{minimal}
  2. \usepackage{expl3}
  3. \ExplSyntaxOn
  4. \begin{document}
  5. \tl_if_novalue:nTF{\c_novalue_tl}{PASS}{FAIL} % prints FAIL
  6. \ExplSyntaxOff
  7. \end{document}
