# Trick/hack to prevent work sptting when assigning the output
# of a bash function to an array.
unset v; IFS=$'\n' read -r -d '' -a v < <(_build_AND_regex); declare -p v
#
# IFS=$'\n': This sets the Internal Field Separator (IFS) to newline (\n).
    This ensures that spaces in the output of _my_function won't cause
    word splitting.
# read -r -d '' -a v: This command reads input into the array variable v.
# -r: Prevents backslash escapes from being interpreted.
# -d '': Delimiter option set to an empty string. This ensures that
    read reads until it encounters a null byte (this effectively
    reads the whole output as a single line).
# -a v: Assigns the input to the array variable v.
# < <(_my_function): This redirects the output of _my_function to the
    read command.
