There is an extra comma at the end. That is,
\SEQ X[1,2,3] expands to $X_1,X_2,X_3,$

How can I treat the last element of a commalist differently?
It is much easier to treat the first element as special:
\def\doSEQ[#1][#2]%
    {\ifsecondargument
      \donefalse
      \mathematics{\processcommalist[#2]{\dodoSEQ{#1}}}
    \else \mathematics{\bold{#1}}\fi}
\def\dodoSEQ#1#2%
    {\ifdone ,\else \donetrue\fi#1_{#2}}
Thanks Taco,

  Works like ... er ... magic. Where is \done set to true?
