Concatenate all arguments and wrap them with double quotes

Question

function foo() {
A=$@...
echo $A
}

foo bla \"hello ppl\"

I would like the output to be:
\"bla\" \"hello ppl\"

What do I need to do in

Answer 1

@msw has the right idea (up in the comments on the question). However, another idea to print arguments with quotes: use the implicit iteration of printf:

foo() { printf '"%s" ' "$@"; echo ""; }

foo bla "hello ppl"
# => "bla" "hello ppl"
