You forgot a lot of other globals, like $STDIN and %ARGV.

If we want to rewrite Perl, fine.   Failing that, not fine.

Those twenty files are irrelevant.  You cannot expect to 
be able to go around CHANGING EVERYBODY ELSE'S CODE.  And 
that is where my concern resides.  It is not in the code
in the distribution, about which I couldn't care one whit less. 

>why the outrage?

Because it is arrogant to make these high-and-mighty decisions
about how people "should" be programming just so that they'll
conform to *your* puritanical maxims.  

I have a much better idea: go learn what $a and $b are for in sort
routines.  I'm sure you'll find that to be much easier than changing
the world.  

THOU SHALT NOT SCREW WITH EXISTING CODE.
