"class attrdict" is a perennial dead-end for intermediate pythonistas who want to save 3 characters/5 keystrokes for item access. Other languages such as javascript allow "somedict.foo" to mean the same as "somedict['foo']", so why not python? Well, there are a number of reasons why not, beginning with all the magic method names in python.<div>

<div><br></div><div>The "foo" part would of course have to obey attribute/identifier naming rules. So there would be no shortcut for "somedict['$#!%']". But for any identifier-legal foo, the interpreter would just read ..foo as ['foo'].</div>
<div><br></div><div>I would not be surprised if I'm not the first person to suggest this. If so, and there's already well-known reasons why this is a bad idea, I apologize. But if the only reason not to is "we never did it that way before" or "it would be too addictive, and so people would never want to use older python versions" or "headache for tools like pylint", I think we should do it.</div>
