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 https://wiki.contextgarden.net/System_Macros/Comma_Separated_Lists

Maybe a bug?

More a feature as \define defines a protected macro. \starttext \define\somelist{foo,bar,baz} {\tt\meaningasis\somelist} \getcommacommandsize[\somelist] \commalistsize \defineexpandable\somelist{foo,bar,baz} {\tt\meaningasis\somelist} \getcommacommandsize[\somelist] \commalistsize \starttexdefinition protected somelist foo, bar, baz \stoptexdefinition {\tt\meaningasis\somelist} \getcommacommandsize[\somelist] \commalistsize \starttexdefinition somelist foo, bar, baz \stoptexdefinition {\tt\meaningasis\somelist} \getcommacommandsize[\somelist] \commalistsize \semiprotected\def\somelist{foo,bar,baz} \getcommacommandsize[\somelist] \commalistsize \getcommacommandsize[\semiexpanded{\somelist}] \commalistsize % also in next version: % % \starttexdefinition semiprotected somelist % foo, % bar, % baz % \stoptexdefinition % % {\tt\meaningasis\somelist} % % \getcommacommandsize[\somelist] \commalistsize % \getcommacommandsize[\semiexpanded{\somelist}] \commalistsize \stoptext The semiprotected is something lmtx and only expands when explicitly asked for (like in an \edef or so). Something that we might apply in the core some day.
