Ah! That reminds me of something I have been experimenting with...
Quick example:
>> Data: [4 7 2 9]
== [4 7 2 9]
>> New: rejoin [
[ {Here's the data:} newline
[ foreach TMP Data [append {} join TMP { }]
[ newline newline
[ {Here's the data * 5:} newline
[ foreach TMP Data [append {} join TMP * 5 { }]
[ ]
== {Here's the data:
4 7 2 9
Here's the data * 5:
20 35 10 45 }
