Hello all,

Consider the following:

\documentclass{article}
\usepackage{expl3}
\begin{document}
\CodeStart
\def\temp{a~b~c}
\err_info:nn{\temp~stuff}{}
\err_info:nn{\temp\ stuff}{}
\err_info:nn{\temp\~stuff}{}
\err_info:nn{\temp\c_space_token stuff}{}
\err_info:nn{\temp\space stuff}{}
\CodeStop
\end{document}

Only the last one works as intended (by me).  Is there a LaTeX3 way to
do this?
