Yes, but foreach loops don't allow indices to be non-int. I still haven't
fixed that.

Yes, when there was no nesting, and appends were done as toplevel-
statements the thread ids were number like "2" , "0" but when I modified the
parser to allow appends to be done inside loop-bodies the thread indices
turned out to be like "0-1-3" , "1-0-3-2-1" etc.. and key collisions are
happening. Wasn't thread prefixes supposed to be unique ?
