You might know this already, but "Bash in POSIX mode" is not quite POSIX. For
example, arrays are not defined by POSIX:

http://mywiki.wooledge.org/Bashism#Arrays

Yes Bash even in POSIX mode handles them:

    $ bash --posix -c 'z=(2 3 4); echo ${z[2]}'
    4

Dash rightfully does not handle them:

    $ dash -c 'z=(2 3 4); echo ${z[2]}'
    dash: 1: Syntax error: "(" unexpected
