Ok, I fear I wasn't quite clear about the idea and I don't even know
whether any of those patterns make much sense the way I liked to play it
through, but here it goes...
In a way, I wanted to make *a macro* agnostic to whether or not it is fed a
variable or a parameter... don't ask me why, that was the ball being played
:)
Something like (watch out, pseudo-syntax)...
\define macro(foo)
<$if $foo$>
do this
<$else>
<$if <<foo>>>
do that
<$else>
otherwise this
</$else>
</$if>
</$else>
</$if>
\end
...but that other usecase where a single variable or parameter has
different values is a lot more interesting...
\define macro(foo)
<$if match="$foo$" value="bar">
do this
<$else>
<$if match="$foo$" value="baz">
do that
<$else>
otherwise this
</$else>
</$if>
</$else>
</$if>
\end
So, that's two entirely different games being played :)
Something tells me that that's almost like the reveal widget, except that
reveal only works by checking against states, rather than checking a param
or variable against something else.
Best wishes, Tobias.
