Strict is _not_ a newbie pragma. Together with
'use warnings;' or '-w' it can save you hundreds of hours
of debugging. When I'm interviewing a prospective applicant
for the shop I work at, and I look at the applicant's code,
a failure to use strict is almost always grounds for a
negative recommendation. It's simply irresponsible practice
to program without it.
You don't need an 'expert_mode' pragma, BTW. There's already
a 'no strict;' that you can turn off for blocks in which you're
going to be using symbolic references or something.
I agree that strict should on by default, but one of all of
my 5-liners will always be 'use strict;'.
