As a datapoint: in my zshrc, I have 12 wrapper functions of the «foo()
{ command foo "$@" }» form, and only one function that would benefit
from the proposed compdef enhancement.

That function takes 'git rev-list' arguments and runs 'tig' (a Git
history viewer, like gitk) on them:
.
    mytig() {
      if (( $# )); then
        tig --no-walk $(git log --pretty=%H "$@")
      else
        tig --date-order --all -150
      fi
    }

Writing a completion function for this helper today is a little tricky,
since 'autoload +X _git' doesn't define _git-log().  Under the proposal,
defining completion for this helper would simply be «compdef mytig='git
log --pretty=%H'».  (Or whatever syntax is decided on)

Cheers,

Daniel
