  > Allowing explicit braces fixes deficiencies in python's grammar. For example, multi-line lambdas aren't currently possible in python. I'd clarify that to "lambdas can't contain statements". Lambdas can contain expressions, which can be nested arbitrarily, have side-effects (e.g. tuples guarantee left-to-right evaluation of elements), and be spread across multiple lines. It's not exactly pretty though ;) I wrote about this a few years ago at http://programmers.stackexchange.com/questions/99243/why-doesnt-python-allow-multi-line-lambdas/252546#252546 http://programmers.stackexchange.com/questions/99243/why-doe... and slightly more obtusely at http://chriswarbo.net/blog/2012-11-17-anonymous_closures_in_python.html http://chriswarbo.net/blog/2012-11-17-anonymous_closures_in_...
