The only point I can think of that merits the term "badly implemented" is the lack of
proper garbage collection. The fact that objects cannot be garbage collected when they
contain circular references is IMO a major weak point in Python (I wonder wether Python 
2.0 will get rid of reference counting?).   
But these are indeed *extremely* complex tradeoffs: if introducing proper garbage 
collection means giving up easy portability and ease of writing extensions 
in C/C++ we can do without.
