Package: bash
Version: 3.1dfsg-7
Severity: normal
"typeset -r" will make a variable readonly. From bash(1):
-r Make names readonly. These names cannot then be
assigned values by subsequent assignment
statements or unset.
The man page then goes on to say:
Using `+' instead of `-' turns off the attribute
instead, with the exception that +a may not be used to
destroy an array variable.
This means I should be able to "typeset +r" to undo the "-r", but it doesn't:
------------------------------------------------------------------------
(debian) chris@chrislap:~$ var=xxx
(debian) chris@chrislap:~$ echo $var
xxx
(debian) chris@chrislap:~$ typeset -r var
(debian) chris@chrislap:~$ var=yyy
bash: var: readonly variable
(debian) chris@chrislap:~$ typeset +r var
bash: typeset: var: readonly variable
(debian) chris@chrislap:~$ var=yyy
bash: var: readonly variable
(debian) chris@chrislap:~$ echo $var
xxx
------------------------------------------------------------------------
I don't know if this is a documentation bug or a bash bug, but one or
the other seems to be wrong here.

I don't know if this is a documentation bug or a bash bug, but one or
the other seems to be wrong here.
The documentation was incomplete. It now says:
Using `+' instead of `-' turns off the attribute instead, with the
exceptions that +a and +A may not be used to destroy array variables
and +r will not remove the readonly attribute.
