I wonder if my performance issues relate to re-calculating an object
over-and-over again. I tried something like this

    save = moduleX(x);

    for (i := [1:10000])

        translate(some function)

                 save;

that did not work syntactically, so I have to use

    for (i := [1:10000])

        translate(some function)

                 moduleX(x);

Should I enclose module(x) within render() to get

    for (i := [1:10000])

        translate(some function)

                 render(moduleX(x));

or define moduleX(x) as

    moduleX(x)
    	render()
    		some code

The last case because render() is a module that causes its children's
geometry to be calculated by CGAL and cached.

Or you could do

for (i := [1:10000])

translate(some function)
render()
moduleX(x).
