Problem description

81dd496 breaks stderr after exiting a subshell. I use this all over my place in my dotfiles so I can have self contained functions and it has destroyed my workflow (as I no longer see errors about undefined functions or incorrect commands).

Before:

After:

Reproduction steps

$ echo "test" > /dev/stderr

$ (exit)

$ echo "test" > /dev/stderr

My .zshrc:

fpath+=(~/.zfunctions)
autoload -U promptinit
promptinit
prompt pure

Hi @nathanchance, I've been unable to reproduce this. There's been similar issues before #547 and mafredri/zsh-async#35, but these should have been fixed in zsh-async >= v1.8.1. You can check which version you have via echo $ASYNC_VERSION.

[nathanchance]

Well that would certainly make sense since it seems that the version of async.zsh that is bundled in this repository is 1.8.0 :)

If I manually update async.zsh to the latest from your tree, the issue is resolved. Thanks for the comment, I will keep the copy updated manually until it is updated here.
