Nothing has changed, except in the weird case where you are
trying to modify a variable through assignment, while,
*in the same statement* you are also trying to modify it
through the side-effect of a function call. In fact,
it's only when there are two or more subscripts on the LHS
that there's a change.

This will break a tiny percentage of existing code, but
I think you'll find the $ feature to be very convenient, 
as well as promoting readability and efficiency.
