Uh .. no.

tab@music4:~ $ perl -de 1 Loading DB routines from perl5db.pl version 1.51 Editor support available. Enter h or 'h h' for help, or 'man perldebug' for more help. main::(-e:1): 1 DB<1> %hash = (); DB<2> use Data::Dumper; DB<3> print Dumper(\%hash) $VAR1 = {}; DB<4> if ( exists $hash{nothing} ) { print "Wow.\n"; } DB<5> !3 print Dumper(\%hash) $VAR1 = {}; DB<6>
For me, the whole point of using exists is to avoid doing autovivification.

But the example used a two level hash .. so I answered the wrong question. Ugh.
