'['#x=x-1
']'#x=x+1
_#x=x
maximum.scanr(#)0

Usage example: maximum.scanr(#)0 $ "[1, [[3]], [5, 6], [[[[8]]]], 1]" -> 5.

Haskell doesn't have mixed lists (Integer mixed with List of Integer), so I cannot exploit some list detection functions and I have to parse the string.

Im starting at the right with 0 and add 1 for every ], subtract 1 for every [ and keep the valuesvalue otherwise. scanr keeps all intermediate results, so maximum can do it's work.
