Subject: indirect array element assignment?
Date: Sat, 02 Jul 2022 06:33:40 -0400	[thread overview]
Message-ID: <11ca04c9-1503-4cd2-a44b-635dc53e43a8@www.fastmail.com> (raw)

What's the best zsh way of doing an indirect array element assignment?   This works quite nicely in bash: 

fruits=("apple" "banana" "carrot")
# but a carrot is not a fruit
declare -n v=$var
echo ${fruits[@]}
=> apple banana cherry

Everything in zsh I've tried around  ${${(P)v}[2]::=cherry}  with misc different bracketing gets "not an identifier", suggesting maybe the ::= form doesn't support subscripting.   Is there something better than 'eval' for this?
