Python UDFs with Pig (support for Filter functions?)

Quick question from a Pig noob...in 0.11 does Pig support developing filter functions developed in Python? Is there any documentation or examples that anyone knows of?
thx,
John

Now that we have a boolean datatype, filter function is just an evalfunc of

It should work.
filtered_result = FILTER dirty_data udf.my_python_filter_func(field1,
field2);
