Description:
  It's not possible to declare an array that is both global and
associative using declare
  inside a function.

Repeat-By:
  # this doesn't work
  function fun { declare -g -A arr=([A]=1 [B]=2); }; fun; echo
${arr[A]}; unset x
  # => empty output

  # this works
  function fun { declare -g arr=([A]=1 [B]=2); }; fun; echo ${arr[A]}; unset x
  #
