Re: [Python-ideas] Quick idea: defining variables from functions that take the variable name

It could work with indexing, like:

key -> my_dict[]

instead of

key = my_dict[key]

That would have to be

key = my_dict['key']

With the possible exception of the typing module, I don't see when that would be useful.

There are proven uses for passing a name to a function. Any time that an object needs to know its own name, you have to pass it to the constructor. But I can't think of any cases where you would want to do something similar with item lookup.

Or even attribute lookup with a trailing dot:

attr -> my_object.

That fails the "grit on Uncle Timmy's monitor" test. The trailing dot is easy to miss.
