Enjoy your arbitrary command execution.

   Can you give me an example, using the code I posted, where that would happen?

Passing arrays "by reference" (by name) to a function will be possible
in bash 4.3.  It is not possible in current versions of bash, without
using eval trickery, as you have already noted.  And doing it with
eval is so difficult that it's easier to switch languages entirely.

   It is not the least bit difficult with eval:

eval "array=( \"address@hidden" )"
