Passing children to modules that don't accept them doesn't issue warning

[kwikius]

module Ring(outerD,innerD,thickness){
 epsilon = 0.1;
    difference(){
        cylinder(h = thickness, d=outerD , $fn= 20)  //;
// NO STATEMENT TERMINATOR ";" in above line      ^^^  BUT DOESNT FAIL COMPILATION
// No warning
// next statement is  ignored...
        translate([0,0,-epsilon]){
          cylinder(h = thickness + 2 \* epsilon, d=innerD, $fn= 20);
       }
   }
}

Ring(100,80,10);

Some modules take children, some modules don't

consider

translate([10,10,10]) cylinder(h=1, d=2);

then

cylinder(h=1, d=2) translate([10,10,10]);

In your example above its not that the statements following cylinder are ignored, its that you are passing those as children to the cylinder module (which makes no sense)

So it cannot be a syntax "error", but we can issue a warning when you try to give children to built in modules that don't accept children (I think)

Thanks for the reply.. I Changed issue title to reflect your comments

I would call it something along the lines of "Passing children to modules that don't accept them doesn't issue warning" it doesn't really have anything to do with the statement terminator, nor the difference module specifically.

Done!
