Is there a good way to test for a minimal ZSH version in a shell
script?

I tried
      if [[ $ZSH_VERSION -ge 5.3]] then
          echo yes
      fi
but that fails if the version has more than one decimal point (e.g.
5.5.1).

You should be able to do

autoload -Uz is-at-least
if is-at-least 5.3; then
  ...
fi

Thanks, Peter (and Daniel), perfect!
