No. I just guessed.
I think I might have read it in the source the other day too.

I'll take a look at the wiki now:
http://www.zope.org//Members/pje/Wikis/ZPatterns/SkinScriptSyntax

  expression

  A DTML-style Python expression. As with DTML, the "_"
  object is available for access to Python built-ins and
  library functions. 

Aha!

I'm looking forward to using the new "OTHERWISE LET" clause too, when
the next release of ZPatterns comes out.

Thanks.
