Many wonderful comments have already been given. Here are some nitpicks
that will no longer matter once you stop writing this program in bash,
which is a poor choice for this particular job.

The quoting here is incorrect. It should be:
for iZ in "${!_ar_terms[@]}"; do
You probably got away with it because you haven't used indices that
contain whitespace yet. (I'm not even sure whether you're using an
indexed array, or an associative array. Obviously with indexed arrays,
your indices are always integers, so the improper quoting won't be
able to bite you -- but that changes as soon as you use an associative
array where the indices can be arbitrary strings.)
Also, do not use all-caps variable names for regular variables. All-caps
names are reserved for environment variables and special internal shell
variables. Use at least one lower case letter in each variable to avoid
collisions with reserved names.

Here, the .* (or at least the *) should be quoted too. Otherwise, the *
is part of a live glob that could potentially match filenames in the
current working directory, which would break the script.

That's definitely NOT what you want.
unicorn:~$ args find . -iregex ".*$x"
4 args: <find> <.> <-iregex> <.*rc>
That's what you want.
