Damian Conway is working on a book on "Perl Best Practices", which
I believe he said would be published sometime soon.  I think it
would be fair to describe the material as conventions and guidelines
for Perl.

A quick look at CPAN turned up Filter::Macro
(http://cpan.org/authors/id/A/AU/AUTRIJUS/), which is a source filter
for making macros which are expanded inline.

Along the way, I was intrigued to find the "Inline" module
(http://cpan.org/authors/id/I/IN/INGY/), which provides the ability
to write Perl subroutines in other languages (analogous to the
support some C compilers provide for inline assembly language).
