Once field names become interesting, e.g. the output from JSON with dots etc, I find it easier to use the dictionary notation. (Not sure if its really called that).
Its a few more chars to type, but seems bombproof.
Configure fields:
out1['Feed Identifier'] = unicode
Process Records:
out1['Feed Identifier']= 'xyz'
