Bash Version: 4.0
Patch Level: 28
Release Status: release

Description:

A bash function with a dot in its name can be created and used with no
problems but cannot be removed - the "unset" command chokes on the name.


Repeat-By:

This sequence yields the expected results:

    function f() { echo $FUNCNAME ; }
    f
    unset f

...while this sequence fails during the unset phase with the complaint
that the name is not a valid identifier:

    function f.dot() { echo $FUNCNAME ; }
    f.dot
    unset f.dot
