These appear to be long-standing problems (since v2.6 at least), and 
they're still around as of v4.0.4, and they're not in the known-bugs 
FAQ, and they seem to be platform-independent.

Bug I
=====

Bad Things happen if I assign a name to an alias and then to a function.

     $ which echo
     echo: shell built-in command
     $ alias foo='echo bar'
     $ foo () { echo baz }
     $ which echo
     echo () {
             echo baz
     }

Of course Very Bad Things now happen if I try to use `echo' or `foo'.


Bug II
======

     $ /bin/sh -c 'echo out; echo err >&2' 2>&1 >/dev/null
     err
     $ /bin/sh -c 'echo out; echo err >&2' 2>&1 >/dev/null | cat
     err
     out


I have reproduced both of these bugs on these platforms:

     RedHat 7.2 GNU/Linux (heavily CERN-customised), zsh 4.0.4
     RedHat 7.1 GNU/Linux, zsh 3.1.6-dev-22
     SunOS, zsh 2.6-beta4
     HP-UX, zsh 2.6-beta21
