Re^2: Traversing through HoH

I think I want to make my code less wordy.. for example, I would prefer:

print map $_,"\t",$hash{$_},"\n", sort keys %hash
[download]

the above code as compared to

foreach my $key (sort keys %hash){
    print $key,"\t",$hash{$key},"\n";
}

Um, that seems kinda-sorta-premature, but if you think in terms of map (see map and grep or clear code? ), great , map it up to the max -- were you really after this (your original question)? `for my $val ( map { values %$_ } values %hoh ){ ... }` [download] This thread reminded me I wanted to read about skimmable code / Skimmable Code & end-of-block comments	[reply] [d/l]
