Re^2: Possible for Map to create Hash of Hash?

[FloydATC]

It's almost always useful to explore other ways to express yourself, be it in english or in Perl. Whether or not it is wise to use those newfound expressions in public or production is an entirely different discussion.

So, it turns out that map() seems like an awkward way to create a Hash of Hashes. That's fine. Simply seeing map() used in different ways can help to unlock its usefulness, by seeing it put to use. It certainly did for me.

Earlier today I learned about a new and bizarre way to use glob() for calculating permutations. The code was nearly incomprehensible and I'd never actually use it for anything but new and interesting ideas were sparked.
