Oh, now I am definitely in favor of .[]! I read it in gmail in FireFox which uses a small variable-pitch font whose dot is a single pixel. The .() example was hard to find; the .[] jumped out immediately. (When do you ever see self[anything]?) Raymond's -> suggestion was nice.

I think it's gets a bit awkward in some situations.

if bar->'__%s__' % attr < -42: print 'Hello World'

if bar.['__%s__' % attr] > -42: print 'Hello World'

To me it's easier to parse the second one visually.
