Re: defineitemgroup interferes with item reference

Though there's no problem without those references in [brackets], so the
mixing works most of the time anyway.

Thanks!  With two small changes, your definition makes the mixing work
even when using references.  The two changes: (1) the macro needed a
closing brace, and (2) there's no \currentitemlevel in any context
source file so I guessed that \itemlevel was the intention.  So:

\def\dostartitemgroup[#1][#2][#3]%
   {\bgroup
    \ifnum\itemlevel=\zerocount
      \def\currentitemgroup{#1}% no nested mixing of itemgroups
    \fi
    \ifthirdargument
      \dodostartitemgroup[#2][#3]%
    \else
      \doifassignmentelse{#2}
        {\dodostartitemgroup[][#2]}
        {\dodostartitemgroup[#2][]}%
}

Is this macro worth putting into the official distribution or is it a
special hack to keep with my documents that need it?
