Is there a preferred way to use proper folding with python-syntax ?

By "proper folding" I mean not a trivial folding solely indent based but a more decent one based on def, class and # {{{ }}} markers declarations.

I tried to use Python-Syntax-Folding and braceless.vim but none seems to be compatible with python-syntax.

The indent mode of Python-Syntax-Folding suits my needs but lacks python 3 syntax.
