this may be so, but it's a pretty simple slot substitution.  here's the 
five_template.pt from my simplest failing case:

<tal:block metal:define-macro="page">
<html metal:use-macro="here/main_template/macros/master">

  <metal:block fill-slot="main">
    SOMETHING SHOULD BE HERE
  </metal:block>

</html>
</tal:block>

the add.pt pulls in this template's "page" macro correctly, and is able 
to fill slots (when i define them) on this page w/o trouble.  this page 
will pull in main_template's "master" macro, but is unable to fill the 
slots.  i'm pretty sure that in most cases this syntax would work.  whit 
suggested to me that there may be some disconnect in the metal namespace 
across the Z2->Z3 boundary, which sounds reasonable, but as i said i 
haven't had any luck in figuring out where this disconnect might be. 
i've done lots of complex tal/tales/metal coding in my time, but am not 
familiar enough w/ the internals of the tal interpreter to know where to 
look on a problem like this.
