how to pack an integer array to string?

[Liang He]

I want to pack an array such as [1,2,3,4]
to "1234", instead of \001\002\003\004, how to do that?

% irb

x = [1,2,3,4] => [1, 2, 3, 4]
x.join('') => "1234"

enjoy,

I just tried this in irb:

irb(main):112:0> [1,2,3,4].to_s
=> "1234"

I just put eyes on 'pack', not aware that so many workarounds.
Thanks guys!
