Module /Function Parameter Passing By Reference

[rbaumann]

Would it be possible to pass parameters into modules /functions by reference? Having such a mechanism allows writing modules that can significantly enhance re-usability of components. For example imagine the following:

c = 5; // side c of the triangle
b = 4; // side b of the triangle
a = 3; // side a of the trinagle
r = 1; // radius of round triangle corners
h = 3; // hight of triangle
p = [...]; // Coordinates of corner centers and triangle's center of gravity

// create a triangle with round corners and a 2 mm diameter centered hole in each corner
difference () {
3D_TRIANGLE (s1=a,s2=b,s3=c,hi=h,p_arr=p); // module drawing 3D-triangles with rounded corners
translate (p[0] cylinder (r1=1,r2=1,h=5,center=true); // p[0] got co-ordinate of triangle A - corner
translate (p[1] cylinder (r1=1,r2=1,h=5,center=true); // p[1] got co-ordinate of triangle B - corner
translate (p[2] cylinder (r1=1,r2=1,h=5,center=true); // p[2] got co-ordinate of triangle C - corner
}

This doesn't fit into OpenSCAD's language paradigm. We're dependent on modules and functions not having side effects.
