This will be possible in Rubinius, but it requires savaging the source  
code. Is there a way to do it in normal Ruby? Is source code savagery  
required?

Gotta love that about Ruby… you can even kiss a basic class like  
Array goodbye with a single line of code.

I love ruby.

You could probably alias that to :implode.

Hi,

That happens because irb then tries to use an Array internally and it no  
longer exists. In normal Ruby interpreted code, it’ll work fine so far  
as you use no arrays.
