Release Status: release

Description:
If I declare a global read-only variable and I try to declare a local 
variable with that name, I can not create
the local variable.
I expect that local variables can be declared independently for the 
global variables.

Repeat-By:
$ declare -r var=55
$ myfunction() {
> local var=11
> echo "\$var=$var"
> return 0
> }
$ myfunction
bash: local: var: readonly variable
$var=55

Description:
[Assignments to variables with attribute 'integer' behave unexpectedly 
if the right side has not an integer value.
It seems that the value is interpreted as a variable name and expansion 
is done recursively.
This is not what I would expect.]
