Array literals in GEL

[GoogleCodeExporter]

Array literals should be supported in GEL so a user could say, loop through a 
bunch of columns to concatenate their 
contents into single column, for example: 

forEach(["narr1","narr2","narr3","narr4"], v, if(isNonBlank(cells[v].value), 
cells[v].value, "")).join(" ")

Would join the columns "narr1 ","narr2","narr3", and "narr4" into a single 
column. Right now, you just get an error if you try. 

You can accomplish this today with something like:

forEach("narr1,narr2,narr3,narr4".split(","), v, if(isNonBlank(cells[v].value), 
cells[v].value, "")).join(" ")

But it'd be nice to be able to work with arrays as well as strings.

This should probably be an enhancement. I didn't see the option.
