Sure I did, but couldn't figure out how to do it ;)
IMHO it's NOT a regular iterator because operations '*' and '++' are
combined into 'Next'.

I have problems with return value. In __iter__ I have to return self, but
there is no Python self yet in wrapping class.
So probably I have to duplicate part of the BPL iterator guts, but I got
lost :(
