Is there such a thing?
Yes there is.
I'm trying to take a HoH and make a reference to a sub-part of the hash.
This doesn't work:
my %sub_hash = $main_hash{'sub_hash'};
I get the following error:
Reference found where even-sized list expected at ./my_buggy_program line 30.
Any quick tips on how to reference and assign this sub-hash?
my %sub_hash;
@sub_hash{ 'sub_hash' } = @main_hash{ 'sub_hash' };
