Hi, I've just ran into a behaviour that runs against what is shown on the wiki, https://wiki.contextgarden.net/System_Macros/Comma_Separated_Lists Maybe a bug? The wiki says you can use \getcommacommandsize to get the length of a comma separated list, but it does not seem to work. MWE below. Best, Denis \define\somelist {foo, bar, baz} \starttext \getcommacommandsize[\somelist] \commalistsize % Expected : 3 % Actual : 1 \expandafter\getcommalistsize\expandafter[\somelist] \commalistsize % Expected : 3 % Actual : 3 \stoptext
