An annoying consequence is that (contrary to with ksh93) you can't do:

a[""]=foo

To assign an element for the empty key. You have to do things
like:

a[${}]=foo

or

a+=('' foo)

instead.

It would be nice if one could do:

a[]=foo

(which currently returns an error)

Note that it's a lot worse in bash. bash associative arrays
can't have an element with an empty key!
