Got it. Unfortunately, I don't think there is a way to prevent the "_extra"
key from being added to each Row in this case, so .as_list() will end up
including it. You'll either have to remove the "_extra" keys after calling
.as_list(), or write your own function to convert the Rows to a list of
dictionaries.
Feel free to submit a Github issue (to the PyDAL repo, not the web2py repo)
suggesting that "with alias" fields not be added to the "_extra" dictionary
(it appears to be unnecessary, as the alias is already added as a top level
attribute of the Row object).
