@zero323, I think that the decorator and existing UDF factory method should
be the same, but that we can't break existing code. Can you explain why this
necessarily breaks code that relies on returnType as a positional arg? What
about something like this:
```python
@functools.wraps(_udf)
def udf(f=None, returnType=StringType()):
"""A decorator version of pyspark.sql.functions.udf
"""
if f is None:
return functools.partial(_udf, returnType=returnType)
else:
return _udf(f=f, returnType=returnType)
```
