Expansions

Wiz supports Bash parameter expansion, command substitution, arithmetic expansion, arrays, and process substitution. Scalar interpolation converts values to text:

declare -T int port=8080
printf 'port=%s\n' "$port"
declare -T string host="$(hostname)"
((port += 1))

Quotes still control splitting and globbing. "${items[@]}" preserves array elements; unquoted $value produces safety/no-unquoted-expansion with a safe quoting fix.
