note 53047 deleted from control-structures.foreach by googleguy

Note Submitter: flobee at gmail dot com ---- be aware! take the note in the manual serious: "foreach operates on a copy of the specified array" when working with complex systems you may get memory problems because of all this copies of arrays. i love this function (easy to use) and use it more often than "for" or "while" functions but now i have really problems on this and finally found the reason (which can be a mess to find out)! the sum of memory usage sometimes can be *2 than you really need.
