Hi friends,
When i use a iterato i asume it is well done, (no body realy see the doc)
my proposal: for all iterators we define a BREAK macro
as sample
#define iterate_outward_break break
if iterator is a double loop we define it as someting making a error at
compile time and a warnig to coder

best regard
Marcelo
