I misread this, sorry. This might work for collections.namedtuple, but is probably not worth the hassle or churn of changing it. The main reason I switched to ast for namedlist is because generating the text version of __new__ or __init__ with default parameter values was extremely difficult, so an approach of exec-ing that one function wouldn't work for me.
