[Petal] [BUG] can't set variables to static values

[Steve Purkis]

Hi,

This is a bug report for Petal-0.92.  I haven't been able to find a way 
to set variables to static values (without writing any plugins).  If 
I'm just being thick, please let me know :-).  Here are some test cases:

   <?var name="set: foo '1'"?>
   <?if name="true: foo"?>ok 1<?else?>not ok 1<?end?>

   <!-- this throws an error -->
   <?var name="set: bar 2"?>
   <?if name="true: bar"?>ok 2<?else?>not ok 2<?end?>

   <span petal:set="baz '3'">
     <?if name="true: baz"?>ok 3<?else?>not ok 3<?end?>
   </span>

The docs on 'define' lead me to believe I should be able to do the 
above (ie: isn't '1' just an expression?)

Regards,
-Steve
