## for loop implicid union.

 Hi, I have this puzzle I'm making:     makepuzzle (pitch=35, theblock = bn, real=1)       {         rotate ([  0,  0,  0]) beam (r=bs, height=bl);         rotate ([  0,180,  0]) beam (r=bs, height=bl);         rotate ([  0, 90, 90]) beam (r=bs, height=bl);         rotate ([  0,-90,-90]) beam (r=bs, height=bl);         rotate ([ 90,  0, 90]) beam (r=bs, height=bl);         rotate ([-90,  0,-90]) beam (r=bs, height=bl);       } where I would like to have the list-of-rotations available elsewhere. So I'm going towards:     makepuzzle (pitch=35, theblock = bn, real=1)       for (i=[0:5])         rotate (lor[i]) beam (r=bs, height=bl); (lor  is the list-of-rotations). but now the "makepuzzle" module has only one child because for does an implicit union. And makepuzzle needs access to all the six children.... IMHO this is why the "implicit" anything is not a good idea. In pascal there is the "writeln" with the implicit newline. As a building block you cannot make a "write" out of that, but the other way around you can easily make a writeln out of "write". Similarly here: If you want a union of your for loop you can easily add the union in front, but the other way around is difficult. Or at least not obvious how to do it for me.         Roger. -- ** [hidden email] ** http://www.BitWizard.nl/ ** +31-15-2600998 ** **    Delftechpark 26 2628 XH  Delft, The Netherlands.
