Snip
With the following code tweaks in Python 2.7.2, I find it works with VERBOSE
for me, but not without.
I would say the regex could still use some more adjustments yet.

If you want just the values back in the order parsed this will work for now.
for match in regex.findall(inp):
for item in range(len(match)):
print match[item]
