Subject: Blocks and variable parameter lists

If I define a block thus:

           { |a|   ...    }

Then 'a' is either a single value or an array, depending on whether it is
called with one or more than one value. Is there a syntax to make it always
be an array even if called with only one parameter? Or do I have to do

    a = [a] unless a.kind_of? Array

Thanks,

Brian.
