OK, I'm with you that this will not be on by default. As you suggest
below, this is something that can (and will) be made an optional mode.

I personally think the default should be to protect certain names, as
that will reduce the chances of new users getting in a mess.

More experienced uses can then elect to unprotect these variables.

I'm all for a special mode, but to do this by default would be backwards
incompatible and yet another incompatibility from Python.


Same here: +1 for special mode, -1 for making this default.

Maybe we could make a "New user" checkbox in the notebook like the "Typeset" checkbox, which turns on protected mode, automatic variable names, and implicit multiplication?
