Just a further note, there is a reason + is not concatenation for arrays.

does "1" + "1" = "2", or "11"? In some languages, both are possible 
outcomes, and which one is used depends on subtle differences in the 
context.

With a specific operator to mean concatenation, the intent is clear. I 
would recommend you stick to using ~ for concatenation, even for your 
own types.
