There is the remaining issue of what exactly the syntax would be. I propose to extend the from clause to allow one or more dots before the dotted name, and to make the dotted name optional if at least one leading dot is found. I propose not to change from-less import. Examples:

from .foo import bar from .foo.bar import xxx from . import foobar as barfoo from ..foo.bar import * from ... import foobar, barfoo Grammar change (see Grammar/Grammar): dottedname: NAME ('.' NAME)* | '.'+ [NAME ('.' NAME)*]

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
