it already would have been implemented this way, but c++ is not my

ok, i tried for testing getRoundness() method, which needs a python  
list as argument, so i tried:

1.)
.def("getRoundness",&pyBodyContainer::getRoundness,(python::arg("excludeList")=python::list),"Returns  
...

-> /home/me/YADE/trunk/py/wrapper/yadeWrapper.cpp:868: error: expected  
primary-expression before ')' token

2.)
.def("getRoundness",&pyBodyContainer::getRoundness,(python::arg("excludeList")),"Returns  
...

-> compilation ok, but running replaceByClumps-example.py said:

ArgumentError: Python argument types in
    BodyContainer.getRoundness(BodyContainer)
did not match C++ signature:
    getRoundness(pyBodyContainer {lvalue}, boost::python::list excludeList)

while using getRoundness() instead of getRoundness([])

hmpf!
