In the parallel branch, I have already answered. Replace lines 272-273 in cipher.py in another way:

        r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&\s*.*\|\|\s*(.*)\(',
        r'\([a-z]\s*=\s*([a-zA-Z0-9$]{3})(\[\d+\])?\([a-z]\)',

and change line 288 nfunc=re.escape(function_match.group(1))),
To make it work, 272-273 have to be
r'a\.[a-zA-Z]\s*&&\s*$[a-z]\s*=\s*a\.get\("n"$\)\s*&&\s*'
r'$[a-z]\s*=\s*([a-zA-Z0-9$]{2,3})(\[\d+\])?\([a-z]$'          

very nice !
