OpenSCAD is very powerful, but its also very limited, because variables can only be assigned once and trick workarounds are required to overcome this shortness. Why dont use another interpreter - like Python ?

Python has all the options you like and you can do clever things before rendering your 3D shapes( e.g. calculate the bits of an QR code)

This Variant is still under heavy development, but it already available for testing. Following commands are already available. My plan is to implement all of them and even more

These are the commands which are already available:

cube cylinder sphere

translate rotate

union intersection difference

square circle

linear_extrude rotate_extrude

A possible working program looks like

def foot(x,y):

c=cube([1,1,10])

return translate(c,[x,y,0])

def plate():

return cube([11,11,1])

parts=[]

parts.append(translate(plate(),[0,0,10]))

for y in [0,10]:

for x om [0,10]:

parts.append(foot(x,y]))

output(union(parts))

Have a look at its web page. it is at http://www.guenther-sohler.net/openscad
