zsh: use completions for command X when I type command Y

문제
In zsh, I have a function called g
which acts like this:
- with no arguments, call
git status
- with one or more arguments, delegate to git with all given arguments - i.e. call
git $@
I would like the tab completions for g
to be exactly the same as for git
. I can achieve this with alias g=git
, but that doesn't allow me to call status
by default (the first point above).
How can I delegate to the completion for git
?
In bash, I simply did complete -F _git g
which re-uses git's completion function. With zsh, git's completion looks much more complex, and I wan't able to find a similar solution.
I'd guess there's some function in zsh to say "pretend I typed command [x], what would you complete it to?". If I knew what that was, it should be simple enough to use a function to delegate to it. But I've found no such function in the manuals.

The documentation for compdef
says this:
The function
compdef
can be used to associate existing completion functions with new commands. For example,compdef _pids foo
But adapting it (_git
is the usual completion function for git) did not produce a working result for me (even after _git
had been autoloaded):
compdef _git g
I was able to get it to work via _dispatch
though:
compdef '_dispatch git git' g
