This seems to be buggy. When I put stat in a function, and declare a
variable that is used as the -A option of stat. Nothing will be saved
in the variable.

function f {
  declare -A fstat
  stat -A fstat "$1"
  declare -p fstat
}

$ f file.txt
declare -- fstat


If I use it as, the variable is still accessible outside the function.

function f {
  stat -A fstat "$1"
}

f file.txt
declare -p fstat

I think the variable scoping should be fixed.

In the first case, `declare -A fstat` in a function, should not affect
the result of stat. But that variable should not be available outside
the function.
