Just making clear that this works along Joseph's lines:

     \newcommand{\MyMacro}[2][]{%
         \@for\my at temp:=#1\do{%
             \@usename{MyMacroOption:\my at temp}%
         #2}

... with some

     \newcommand{\DeclareMyMacroOption}[2]{%
         \@namedef{MyMacroOption:#1}{#2}}

     \DeclareMyMacroOption{item-1}{<item-1-stuff>}
     ...

So \DeclareMyMacroOption is just like \newcommand -- without guarding, 
without macro parameters, without backslash, similar to the commands that 
\label and \ref generate.

HTH -- Uwe.
