Subject: RE: hash of hashes-- preserve insertion order
Isn't it as easy as creating a separate @array that you push the keys into
as you build the hashes?

Title: hash of hashes -- odd behavior
Peter,
On the line:
foreach my $bucket (sort {$a <=> $b} keys
%{$mttr_total{$abrv_grp}} )
You have the
variable “$abrv_grp” but on the previous foreach you use the variable $group. If
you change $abrv_grp to $group it should work.
Title: RE: hash of hashes -- odd behavior
That was it!!! I am using $group as a whole name and $abrv_grp as an
abbreviation of $group. Sometimes its not the data that's convoluted, its the
programmer. Thanks for the keen eye. Curious that this worked at
all.

Title: RE: hash of hashes -- odd behavior
I should say, I have also printed a debug line when this bit of data is added to the hash of hashes too, and it is there.

You swapped a brace with a bracket and didn't you mean this anyway:
$i_ama_hash_ref->{ima_key2}->{"I'm a key"}="I'm a value";
and don't forget, when it get's multidimensional you can drop the ->

Thanks Ron, I've tried your recommendation on another piece of test
code and it works the way I want. I guess the autovivication thing in
this context can be regarded as just another Perl feature, for now at
least.

Defined/Exists is NOT the issue here.
To paraphrase 'exists' entry in Camel 3 (but not Camel 2 or online docs):
When you say...
if(defined (((or exists $Hash{'Key1'}->{'Key2'} {'Key3'}){...
... Perl autovivifies the hash references $Hash{'Key1'} and
$Hash{'Key1'}->{'Key2'}.

What
you describe there is a list of hashes
my
@mother=();
$mother[1]=%hash
$mother[2]=%hash2
however a hash of hashes is possible.
%hash1=(name=>'fred');
%hash2=(name=>'bill');
%mother_of_hashes=();
$mother_of_hashes{myhash}=%hash1;
$mother_of_hashes{yourhash}=%hash2;
Thus
$name
14 matches
