In our document [1] where we lay out the vision for new string and list
processing steps, I think perhaps we missed adding a join() step for lists.
We do list a concat() step in the lists column but that is not quite the
same, and also, concat() as specified does not support a local scope
modifier. I envision wanting to do:
```
g.inject([1,2,3,4,5]).join(';')
```
and getting back
```
1;2;3;4;5
```
What do you think?
