What's the difference between "perl" and "Perl"?  


One bit. Oh, you weren't talking ASCII? :-) Larry now uses "Perl" to
signify the language proper and "perl" the implementation of it, i.e. the
current interpreter. Hence Tom's quip that "Nothing but perl can parse
Perl." You may or may not choose to follow this usage. For example,
parallelism means "awk and perl" and "Python and Perl" look OK, while "awk
and Perl" and "Python and perl" do not. But never write "PERL", because
perl isn't really an acronym, apocryphal folklore and post-facto expansions
notwithstanding.
