Found out that the declare statement does not properly set all variable
flags before assign values:
unset arr
declare -i -a arr=(1 2 3)
declare -p arr
declare -ai arr=([0]="1" [1]="2" [2]="3")
this is ok
declare +i -a arr=(hello world)
declare -p arr
declare -a arr=([0]="0" [1]="0")
this is not ok as arr assignment was handled as integers
It's an interesting order-of-operations question. You can make a case that
the shell should unset the attributes before expanding the words in the
compound assignment statement, since we special-case setting the attributes
for declaration commands. Let me look at that.
