Subject: Re: Handling of arbitrary length arrays in arguments to printf builtin

I guess you'll have to select the elements from the array.

AFAIK, the Array#* in only used to pack and unpack arrays into
argument lists (and other kinds of lists).
For example:

def multiple_returns
  1, 2, 3, 4
end

a = multiple_returns # a=1
a, b = multiple_returns # a=1, b = 2
a, *b = multiple_returns # a=1, b = [2,3,4]

Hope you'll get less n00b =P

cheers!
