quote interpretation via vars without eval

[Alex fxmbsw7 Ratchev]

i was doing declare -p to again modifications, and noticed i can include
quotes inside the declare settment ( declare [-opts] "$res" )
where else do the quotes get interpreted, can you write a short list ?

you know, backslashes, quotes, etc, in vars, as arguments, dont get
interpreted without eval
but with eval its dangerous

so thats why im looking for alternative ways
