in thread Fastest way to compare multiple variables?

I too couldn't resist. A single walk through the hash's keys is the fastest way I could think of doing this:

sub dkubb_compare { my $data = shift; my $first = @{$data{scalar each %$data}}; while(my $key = scalar each %$data) { return 0 unless $first == @{$data{$key}}; } return 1; }

IMHO, it's a little too obscure to be used in production code, but I think it still is a neat idiom.

[james28909]: like all the subs calling get_data get_array get_ect, you could just use get_data. once you send the data to get_data, check if it is a hash or an array ect. and do functions for each, in one sub
[james28909]: that looks like it would be alot more work than just renaming the sub though lol
[Lady_Aleena]: james28909, did you even look at the subs?
[james28909]: yes
[Lady_Aleena]: And you see how the first two are vastly different than the third, right?
