[Help-bash] using functions passed as environment variables after the vulnerability fix

[Wendy Palm]

We updated our system to the latest fix, but find passing functions via an 
environment variable isn't working at all.
Was that the intent of the fix?  Or am I trying to do it incorrectly?

It's a CentOS 6.5 system, with bash-4.1.2-15.el6_5.2.x86_64

# env 'x=() { echo "functions still work"; }' bash -c x
bash: x: command not found
