Append to a commalist

["Fredrik Sjunnesson" <Fredrik.Sjunnesson@acobiaflux.se>]

Hello,

Is there a smart way to create a commalist?

I want to get the equivalent of

\setparameter[namespace][listname={item1,item2,item3}]

but be able to append one item at the time, like

\append{namepace}{listname}{item1}
\append{namepace}{listname}{item2}
\append{namepace}{listname}{item3}

I have tired this:

\def\append#1#2#3{
  \fullexpandoneargafter\doifemptyelse{\getvariable{#1}{#2}}
  {\edef\tmp{#3}}
  {\edef\tmp{\getvariable{#1}{#2},#3}}
  \setvariables[#1][#2={\tmp}]}

but it only works for one list. Apparently \tmp is not expanded so when
an item is appended to one list all other lists are affected. I have
tried \expanded but got the message stack full.

Any help would be greatly appreciated.

/Fredrik
