At least you've discovered Zsh and hopefully its significant improvements over Bash. The only Bash benefit is readarray/mapfile, Z Shell is better in just about every other way.

Unless I'm misreading your comment, zsh does provide similar functionality via zsh/mapfile¹. It, and a lot of other cool stuff, is documented in zshmodules(1).

I believe Bash readarray/mapfile is more like doing this in Zsh:

  lines=( "${(@f)$(my_command)}" )

  lines=( "${(@f)$(<my_file)}" )

which IMO is a little less nice than using a builtin with a name like "readarray".

But this is cool too.
