My cedarnet email was down and I don't know if a response has been
generated yet however this is a detailed account of what is happening
and how to avoid it:
using @list = \%hashed_data stores a pointer to that data. Meaning that
it's not a copy but a link. What you need is exactly what you said... a
copy to a reference. The reason is that each time you go through the
list you are pointing to the same data...
Try this instead:
push(@list, {%hashed_data});
