Python's interpreter variables types differs from types in C in "other
languges", which use with compilers.
Variable's memory organization if different too.
Struct of variables (e.g. integer) on python is complex. This is similar of
struct in C, even more similar of classes in Cpp.
Indexes of LISTs (not arrays) may be [-N...N] . And this is not depend of
usage arcitectures or low level memory organisation, but this depends and
provides only python language standarts.
Python will be work on IBM PC or any microcontrollers (e.g. ARM-based)
absolutely equally.
Indexes [-n] and etc. in python are transformed to expression:
list[-m] => list [len(list)-m]
And usage of this is very relaible. And if its not works - this is bug of
python :)

If you afraids of negative indexes, don't use python!!
Use C, C++ and other languages...
I using python and I will be using python because I see that it is
convenient and flexible.

Does anyone need a gtk frontend?
