One of the big advantages of python in my eyes is we can finally get rid of those annoying braces for statements. I think a solution that brings back the braces would go against using python in the first place. Can the language even handle braces in statements properly? Braces in statements are ignored, and in common usage braces are only used for making dictionaries. In fact the syntax you show is pretty much identical to the syntax for making dictionaries, which I think would be confusing to users familiar with python and would make reading code much harder. -Todd _______________________________________________ PySide mailing list [email protected] http://lists.pyside.org/listinfo/pyside
