For some time now, I've wanted to suggest a better abstraction for the <file> 
type in Python.  It currently uses an antiquated C-style interface for moving 
around in a file, with methods like tell() and seek().  But after attributes 
were introduced to Python, it seems it should be re-addressed.

Let file-type have an attribute .pos for position.   Now you can get rid of the 
seek() and tell() methods and manipulate the file pointer more easily with 
standard arithmetic operations. 

>>> file.pos = x0ae1      #move file pointer to an absolute address 
>>> file.pos +=1            #increment the file pointer one byte
>>> curr_pos = file.pos  #read current file pointer

You've now simplified the API by the removal of two obscure legacy methods and 
replaced them with a more basic one called "position".

Thoughts?
