Thanks for for reply, Rob!
To use the re-declared pi, you just cite it in an expression as normal. The new declaration overrides the earlier one in the subsequent code, but as you are aware, the references to pi prior to the redeclaration remain bound to the original declaration, as in the following example:
So, in the example I gave in my original post, the function `area' is also bound to the first declaration of pi. The re-declaration of pi is available immediately for everything using it afterwards, but NOT the function `area'. Unless I re-declare the `area' function as well.
Is that correct?
