I think this would be an excellent idea. Instead of just giving a "name
error", generate a list of names that it might be close to? Or, if one
appears to be a match excepting for case, ask if that other name might
have been the intended one? A friendly error message!

: Giving people a friendly editor

:learn the unix shell, to be able to manage your source files and run vi, oh
:yes, then you need to learn to use vi, just memorize this table of commands,
:ok, then..."

:So I'd say, please don't change the language itself, but it would be
:interesting to see experiments on a friendly python-oriented editing
:environment (to simplify things like finding modules and documentation,
:importing, reloading, etc.).

Good points!
