Subject: Combination of map and each for hashes
Download (untitled) / with headers
text/plain 547b
There needs to be a more elegant way to run through hash/array pairs. It seems like a few things are almost there, but don't do it in the fashion that it should look. Here's the idea: join("\n", map { "$a => $b" } %hash); In other words, a "natatime" of 2, but arranged as an automatic function, without the need of a while loop. It could be like a reduce function that only reduces it to half of its objects: a reduction of a hash into an array. This can be passed to the other functions that work off of arrays, like sort, grep, join, etc.

Ever took a look into Hash::MoreUtils? As long as I don't know what you're searching for, it's hard to decide whether to move queue or reject :P Cheers

List::Util has pairmap. Try perl -MList::Util=pairmap -E 'say join("\n", pairmap { "$a => $b" } %ENV);'
So I can close this ticket since List::Util already implements a solution.
