[plt-scheme] Namespaces

[pocm@rnl.ist.utl.pt (Paulo J. Matos)]

Hi all,

When I try to use namespace-set-variable-binding! I get:
reference to undefined identifier:
namespace-set-variable-binding!

This function is mentioned in chapter 8 of MzScheme manual. Do I
need to require any lib?

How can I given a function retrieve its name as a symbol?
For example:
(define fib
        (lambda ... blablabla))

Now, I pass it to (foo fib)
I want foo to return fib (the symbol 'fib).

How can I do that?

Best regards,
