Of course there's also no reason to write that specific function that
way.  You can simply do

assign() {
  unset $1
  typeset -g $1=$2
}

The reason for using a named reference would be when you're going do
more things with $var and $value than just assign them, such as
calling another function, or when you want to do something like

append() {
  typeset -nu var=$1
  local value=$2
  # Maybe do something else to $value ?  Then:
  var+=$value
}

Mostly because "typeset" doesn't understand += syntax.
