Subject: [ANN] enumerable-extra 0.1.0

Hi,

Convinced that Symbol#to_proc is mostly a solution in search of a problem,
I've released enumerable-extra 0.1.0.

= What is it?

The enumerable-extra library overrides Enumerable#map, Array#map and
Array#map to accept a method, with optional arguments, that are performed on
every element of the list.

For example, instead of this:

array.map{ |e| e.capitalize }

You can do this:

array.map(:capitalize) # Capitalize every element

You can also mix and match:

array.map(:capitalize){ |e| e + 'x' } # Add 'x' after capitalizing every
element

= Why is it better than Symbol#to_proc ?

First, it doesn't require additional notation, i.e. no "&", no "its", no
"self" - just a method name. In my opinion, that makes the syntax cleaner.
Second, Symbol#to_proc is slow.

= How do I get it?

gem install enumerable-extra

= Caveat

This is for Ruby 1.8.x only.

Enjoy!

Dan
