For purposes more involved than what's shown here, I want to test certain commands having both an ordinary form and a starred form, with the latter constructed using the suffix package. To do that, I pass each form as argument into a macro \try that involves a \csname...\endcsname expression.
For example:
\documentclass{article}\usepackage{suffix}\newcommand{\toward}{\rightarrow}\WithSuffix\newcommand\toward*{\Rightarrow}\newcommand{\try}[1]{$a \csname#1\endcsname b$}\begin{document}OK: $a \toward b$ and $a \toward* b$OK---\verb!\try{toward}! works: \try{toward}BAD--\verb!\try{toward*}! gobbles up the arrow: \try{toward*}\end{document}As shown below, the result of a \Rightarrow b disappears from the output of \try{toward*}
How can that be fixed?
