[Help-bash] How to print a bash variable in the most succinct way?

[Peng Yu]

Hi, x is shown in the following way.

~$ x=(a \' -)
~$ declare -p x
declare -a x='([0]="a" [1]="'\''" [2]="-")'

But the most succinct form should be the following. When I source a
file containing the following line, I got the same array x. Is there
any easy to get a line like the following.

declare -a x='(a "'\''" -)'

Further, is there a way to get the string of "a \' -".
