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

         \@for\my at temp:=#1\do{%
             \@usename{MyMacroOption:\my at temp}%

... with some



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

HTH -- Uwe.
