That worked well, I started trying to get more data from the profile

Is there something I can use to analyze the existing profile output or to

he internal representation is surprising). Basically it
gives the implementor of a Python interpreter the freedom to choose the
internal representation that he deems to be the most fitting. If
implementation details leaked outside that wouldn't be possible anymore.

.
What I am also looking for is a conversion to base 256 (i.e where the
full byte is used and the string and the integer have the same actual
content if on appropriate endian machine), which would make the bit
extraction comparable easy and effective as the i.__hex__() based method.
Using digits()
