Only in posix mode for bash though. I find that POSIX requirement
silly (probably specifies a limiation found in ksh). zsh also
ignores it.

It does error-out when in POSIX mode.
My test case was for the case where the function is defined in
non-posix mode, but type invoked in posix mode.
So, it's a very minor issue as probably unlikely to harm anyone.
