or reshuffle the drawing a bit and clip

\startuniqueMPgraphic{funny}
     numeric h ; h := OverlayHeight ;
     path    p ; p := unitsquare xscaled \overlaywidth yscaled 
\overlayheight superellipsed 0.9 ;
     pickup pencircle scaled \overlaylinewidth ;
     fill p withcolor \MPcolor{\overlaycolor} ;
     draw (20,-1)--(20,h+1) withcolor red ;
     clip currentpicture to p ;
     draw p withcolor \MPcolor{\overlaylinecolor} ;
\stopuniqueMPgraphic
