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:\ 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.
