} Off the original topic, but actually it doesn't, at least not in bash.

I'd forgotten that bash even supports that syntax, but in any case it
does change the type in ksh.

$ typeset -a x
$ typeset -p x
typeset -a x
$ x=( [a]=1 [b]=2 )
$ typeset -p x
typeset -A x=([a]=1 [b]=2)
$ 

Bash allows you to set numerically-indexed positions in a normal array
with the ( [key]=value ) syntax, and also outputs the arrays that way
with "typeset -p".  You can have sparse arrays in bash.
