Hello,
there is an error in the bash documentation:
https://www.gnu.org/software/bash/manual/bash.html#Bash-Builtins
In the 'declare' builtin, option '-n', last sentence:
"The nameref attribute cannot be applied to array variables"
is actually wrong: it can be applied to indexed and associative arrays
(since bash 4.3+)
(tested for bash version : 4.3.48(1)-release (x86_64-pc-linux-gnu))
it can even be applied to functions, except that for calling, explicit
dereference must be given.
Cheers,
Edouard Thiel
