I guess, the %w{ ant bee cat dog talk } must be %w[ ant bee cat dog
talk] as we're talking about arrays and not hashes.
The character following %w can be any "non-alphabetic or non-multibyte character." (I'm quoting from pp. 303-304 in the 2nd Ed.) %w always creates an array of strings, regardless of what delimiter character you use.
Hi David,
Thanks for the information. Actually I'm new to Ruby, and I've not passed
that page yet so...
Best Regards,
Behrang S.

You can try the examples in the book in the interactive ruby shell, irb.
Try running it as
% irb
at your shell prompt and then just paste the examples and see the
results,
