I have not had a chance to look at Flavio's links yet. Since no one who
actually knows rules seemed to be inspired to write an example for me - I
will *eventually* figure it out on my own and post back to the list as an
FYI.
Here is a simple one

Thanks, but this falls into the realm of existing wheels which is a
different part of this project.
All:
I have a for-fun project that I am working on exploring various different
parsers and their methods. So far I have looked at things like
Parse::RecDescent, Parse::YAPP, Parse::Earley, and HOP::Parser. I had
Perl6::Rules on my list, but it is my understanding that
Pugs::Compiler::Rule is
the syntax
looks like for writing an evaluator using rules in p5.
http://svn.openfoundry.org/pugs/perl5/Pugs-Compiler-Rule/lib/Pugs/Grammar/Rule/Rule.pm
- this is the grammar for rules, written in rules.
The last rules have looser precedence; the rules at the start of the
file have tighter precedence
In any case, I was wondering if someone could provide me with an example of
a mathematical expression parser (and evaluator).
To properly compare to the others, it would need to handle the following
operators
+, - (left associative)
*, /, % (left associative)

Hi,

I'm working on a web templating system, and I'm wondering how should I

Hope this is helpful. Corrections are welcome from anyone who spots

My other quibble is that you seem to be prone to stating things in the
negative for at least two of your three tests here:
subtype KeyName of Str where { $_.defined and $_ ne '' and $_ !~ m/\W/ }
and it seems to me that you could simplify all that to
