least for the associative arrays case, because in the case of normal arrays,
ksh93 does some pretty funny things:

Associative is more "default" in ksh93 as in bash:

a=([0]=4)
typeset -p a

gives in bash:
declare -a a='([0]="4")'

in ksh93:
typeset -A a=([0]=4)

An empty array (a=()) gives in ksh93:
typeset -C a=()

-C means Compound variable, which is something different.
