Only started with Perl4 and Perl5 in 1995. I was doing AWK etc for 12 years before that, and resisted switching. I've been doing OO since before C++ hit bigtime, with Objective-C and SmallTalk, so I really like the (no longer new) Perl5 OO style; and the Lispish Map style is also an old friend. What do I hack with Perl? All data that passes my way; systems monitoring scripts at $DayJob, weather data at night, and I cheat on NPR word puzzles.

dumping environment etc from batch perl script
use Data::Dumper;
print Dumper([ # like...
{ X=>$^X}, # which perl
# but not fooled by #!
{V0 => "$]", # perl -v , ditto
V => $^V lt v5.9.0
? q(v).(join(q(.),
(map {ord}
split(//,$^V))))
: "$^V"},
{ ENV => \%ENV} , # like env
# but in actual context
{ INC =>\%INC} , # incomparable
]);
The ugly version of V for Version is to handle 5.6-5.9 v strings and 5.10+ version objects
without knowing which, if you don't want $] to mess up your syntax highlighting and don't want \005 to trip a terminal echoback string when it vString doesn't print.
help them think they understand.
