Verifying behavior of nameref feature

[Jonathan Hankins]

I wanted to verify that this behavior is intended, as I can't find it described in the manual. 

$ echo $BASH_VERSION

4.3.30(1)-release

$ foo=bar

$ echo $foo

bar

$ bar=123

$ echo $bar

123

$ typeset -n foo

$ echo $foo

123

$ echo ${!foo}        # this is what I want to verify

bar

Is using ${!foo} intended to yield the name of the var that foo references, now that foo has been turned into a nameref?  I wanted to use this functionality in a script, but wanted to make sure it was intentional before I rely on it.

Thanks,

-Jonathan Hankins
