How to export array in bash

[Baihao Yuan]

Hi guys,

I wonder how to export arrays in bash. I wrote code like this,
but it didn't work:

declare -ax y[100]
y[3]="thisisatest"
#start a new bash
bash
echo ${y[3]}

#string "thisisatest" expected, but nothing printed

man bash:

BUGS
.....
Array variables may not (yet) be exported.

Well, you can use

array=(whatever foo bar)
export x_array=$(printf '%q ' "${array[@]}")

And in the child shell:

eval "array=( ${x_array[*]} )"

But why the hell would one need to do this?
