Why use expand-word at all then? Modified from a widget that appeared
on the users list some time ago:

  expand-variables() {
    local skip="${(M)LBUFFER%%[ 	\;\|\{\}]##}"
    local word="${(M)${LBUFFER%${skip}}%%[^ 	\;\|\{\}]##}" exp

    exp=${(e)word}

    [[ -n "$exp" ]] && LBUFFER="${LBUFFER%${word}${skip}}${exp}${skip}"
  }
  zle -N expand-variables

Or some such.

Maybe I'll have a look some time...

Setting `zstyle ':completion:*:expand:*' glob 1' works for me.

It is a bit irritating that you have to switch on at least one style
to make _expand do anything...
