 % typeset -A foo=( [zero]=0 [one]=1 [two]=2 [three]=3 [four]=4 )
 % foo[other]='some random $text here'
 % foo[nil]=''
 % print -raC2 -- ${(z)${(*ok)foo/(#b)(*)/${(q)match[1]} ${(q-)foo[$match[1]]}}}
 four   4
 nil    ''
 one    1
 other  'some random $text here'
 three  3
 two    2
 zero   0

(the * in (*ok) requires zsh 5.9, otherwise setopt extendedglob)
