zsh: variable + local + command substitution in array

[tezkerek]

% ./shfmt -ln zsh <<<'IFS=":" local change=($(echo abc:def:ghi))'
<standard input>:1:42: the `local` builtin is a bash feature; tried parsing as zsh

Both of these work, on the other hand:

% ./shfmt -ln zsh <<<'local change=($(echo abc:def:ghi))'
local change=($(echo abc:def:ghi))
% ./shfmt -ln zsh <<<'IFS=":" change=($(echo abc:def:ghi))'      
IFS=":" change=($(echo abc:def:ghi))

How common is this, or what is the utility here? I can see that bash also supports this, but I don't see that it's very useful. For example, with bash 5.3:

$ inline=foo declare d=$inline
$ echo $inline $d

$

The source was this script: https://github.com/indirect/dotfiles/blob/main/dot_p10k.zsh#L1264, used for splitting a string into an array.

I suppose I can replace it with:

local change=(${(@s:#:)change_str})
