I was playing around with the new --help feature and I was expecting it should work for all commands at the interactive prompt.   The local command did not work that way.   Can exceptions be made for the local command?

$ local --help
bash44: local: can only be used in a function
$ f() {
> local --help
> }
$ f
local: local [option] name[=value] ...
    Define local variables.

    Create a local variable called NAME, and give it VALUE.  OPTION can
    be any option accepted by `declare'.

    Local variables can only be used within a function; they are visible
    only to the function where they are defined and its children.

    Exit Status:
    Returns success unless an invalid option is supplied, a variable
    assignment error occurs, or the shell is not executing a function.
