hi,

I've run into a problem which I cannot understand.  I'm working on a 'Foreach'
macro, to process arrays.  it works as expected, except..

the below shows the error message I'm getting when I try to create an object
from within the "payload" macro; first run displays the values supplied from an
array, with the offending line (208) commented out.

zip attached.  (the demo scene is meant to double as draft documentation, hence
the format)
