No, but if you speak Unreadable you can create one quite quickly...

idgroups() {
  emulate -L zsh
  setopt extendedglob
  typeset -gA groups
  groups=(
${=${${(s.,.)${${$(id):#^groups=*}##groups=}}/(#b)(*)\((*)\)/$match[2]\
 $match[1]}}
)
}         

Of course if we had discipline functions blah blah blah.
