On a related and minor note, can we please expand the grammar to allow
from...import statements to continue to the next line after a trailing
comma?  For those of us with large, complex, and componentized projects, it
would be very nice.  e.g.:

from OPAL.Modules.Financial.Reports.COGS import generate, webOptions,
                                                normalize, row_ops,
                                                summary

instead of:

from OPAL.Modules.Financial.Reports.COGS import generate, webOptions, \
                                                normalize, row_ops,   \
                                                summary


This has been a minor nit that bothers just under the threshold of fixing it
myself.  ;)

Thanks,
-Kevin
