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

How do you feel about an arrow operator?

T -> TypeVar() x -> Symbol() T -> type(bases, ns) Record -> namedtuple(fields)

In general:

name [, name, ...] -> callable(...)

where "callable" is some expression, e.g. a name, a dot lookup, etc.

It could work with indexing, like:

key -> my_dict[]

instead of

key = my_dict[key]

Or even attribute lookup with a trailing dot:

attr -> my_object.

instead of

attr = my_object.attr
