No matter how I twist or turn it, "4" does appear in the output.
# With strictures:
use strict;
use warnings;
use Data::Dump 'pp';
my %hash;
$hash{tree} = 4;
$hash{tree}->{apple} = 6;
pp \%hash;
__END__
Can't use string ("4") as a HASH ref while "strict refs" in use at G:\
+x.pl line 7.
# Without strictures:
use warnings;
use Data::Dump 'pp';
my %hash;
$hash{tree} = 4;
$hash{tree}->{apple} = 6;
pp \%hash;
__END__
{ tree => 4 }
No offense, but the real problem is that the OP doesn't seem to understand that the value part of a key/value pair can only hold one value, and consequently the design of his data structure is flawed.
