Aliases that ignore "noaliases"

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

There are some cases where it would be nice to be able to declare an
alias that "always works".  The most obvious recent example would be
  alias nameref='typeset -n'
but also some hackiness in zsh/param/private could be avoided with
  alias private='local -P'

This is important when the alias invokes a keyword rather than a builtin, e.g.
  function private { local -P "$@" }
doesn't parse its argument list the same way.  There are some other
instances where an internally-defined alias that (in particular)
survives "autoload -U" might be useful.

Any thoughts?
