A macro system compatible with dynamic prompt and a word probability

[ema7569]

I have no clear idea about this, it's just to share an basic idea about a macro system

$bottomWithPocket=jeans, pants,
$bottomWithoutPocket=skirt
$jacket=vest, jacket,
$top=shirt, tee shirt,

{$bottom1 |  $bottom2}, {$jacket | $top}

With a conditioning like c++

$BottomWithPocket?Hands in pockets:$bottomWithoutPocket, arms behind back

Of ideally a macro langage?

@If $bottomWithPocket
   Hands in pockets,
@else
   Arms behind back,
