Description:
The array handling is inconsistent across global variables and
local variables. See the Repeat-By for more information.
While this behaviour can be avoided by using 'local -a ...', it
is inconsistent and a cause for confusion. Local's (and declare'd
variables) should at least act like their global undeclared
counterparts without any options specified.
