Good afternoon,
consider the following example:
\documentclass{article}
\usepackage{expl3}
\begin{document}
\ExplSyntaxOn
\clist_set:Nn\l_tmpa_clist{,,foo,bar,}
\typeout{\clist_count:N\l_tmpa_clist} %expected: 5, I get 2.
\typeout{\clist_item:Nn\l_tmpa_clist{3}} %expected: `foo`, I get `'.
\typeout{\clist_item:Nn\l_tmpa_clist{4}} %expected: `bar`, I get `'.
\ExplSyntaxOff
\end{document}
Why does \clist_set:Nn ignore empty items when initialising a clist
variable from a token list? Is this intended behaviour? Is there a
work-around?
Kind regards
Alexander
