[NTG-context] Check if two paths intersect in Metafun

Hi, list. I've got a question about paths and intersections. The following:



path p[];

p[1] = fullcircle scaled 2cm;

p[2] = unitsquare shifted (4cm,6cm);

if (known (p[1] intersectionpoint p[2])):

draw textext("yes");


draw textext("no");




yields an error message: "The paths don't intersect". Is there a way to
intercept this error message and trigger an action instead? Thank you in

Best regards,
