Cool, I tend to use .zsh, but mostly so I know they're not system scripts.

Leaving out the .«tab» saves a little bit of typing. But you might have
already fully tab-completed a couple chars in.

You could tie into the command_not_found_hook (briefly mentioned in
zshmisc(1)). Something like this:

  command_not_found_handler() {
    actual=$@[1].sh
    print "Proxying for actual: $actual"
    for p in $path; do
      if [[ -x $p/$actual ]]; then
        $actual $@[2,-1]
        break
      fi
    done
  }

Then use:

  % foo aa bb
  Proxying for actual: foo.sh
  <regular output>...

A couple caveats:

  * I don't actually do this, but maybe I'll try; the func is not really
    tested

  * zsh syntax highlighting
    (https://github.com/zsh-users/zsh-syntax-highlighting) won't match foo

  * running in cwd as ./foo isn't handled

  * not sure if looping over path is best approach; would something with
    hash work?
